EPSON Product Support Bulletin Subject: Proper Method for Running Benchmark and Diagnostics Programs Date: 06/04/93 Page(s): 1 of 1 PSB No: S-0158 Originator: MWT This bulletin describes the proper method for running any benchmark or diagnostics programs. This applies to any computer system. In most cases, the computer should be started using an MS-DOS boot diskette that’s ‘clean’ - in other words, one with no CONFIG.SYS or AUTOEXEC.BAT files. The appropriate executable can then be run, either from diskette or hard drive. There will be some exceptions to the above rule. In attempting to benchmark or troubleshoot any add-on that requires a device driver (CD-ROM, local area network, etc.), obviously the necessary device driver(s) must be loaded. Also, some programs will require a minimum number of FILES or BUFFERS to be defined in the CONFIG.SYS file. Such programs will usually display this requirement if they are run without the necessary CONFIG.SYS file. For the most consistent results, use the absolute minimal boot configuration that’s allowed by the hardware being tested. Product Support Bulletin Subject: Equity/Apex Compatibility with the SOTA 386si Date: Page: 3/02/90 1 of 3 PSB No: Originator: S-0111 MS ;. CL5 The purpose of this bulletin is to provide the 80386 Accelerator board test results, conducted by the Computer Product Support Center, involving the SOTA 386si from SOTA Technology, inc.

PSB No: S-0111 Page: 2 of 3 Installation of the board in most of the units was quick and simple to do when following the installation instructions accompanying the boards. Installation of the SOTA 386si in the Equity I and the Equity II is rather difficult. Due to the amount of disassembly required, we strongly recommend that only Authorized Service Centers install the board in the Equity I and Equity II. Installation Instructions Equity I 1. Remove the following from the main unit: a) upper case b) rear panel c) front panel d) FDD/power supply block. 2. Follow instructions for a standard installation for the SOTA 386si in an 8088 - based system. Take care to fold the SOTA connector cable so as not to prevent reassembly. The cable is sturdy and will tolerate being folded. 3. Reassemble the main unit and go through the testing and initialization procedure outlined in the SOTA manual. Equity II 1. Remove the following from the main unit: a) upper case b) rear panel c) front panel d) FDD/power supply block. 2. Follow instructions for a standard installation for the SOTA 386si in an 8086 - based system. Take care to fold the SOTA connector cable so as not to prevent reassembly. This will necessitate routing the cable so that it does not conflict with the power connection to the main system board. The cable is sturdy and will tolerate being folded. 3. Reassemble the main unit and go through the testing and initialization procedure outlined in the SOTA manual.

TIonON EPSON AMERICA, INC. Product Support Bulletin Subject: Equity I Computer - Answers to Common Questions PSB No: S-0060A Originator: REMfi Date: 4/23/90 Page: 1 of 8 The following questions and answers have been compiled from the support calls received at the Epson Product Support Center. Floppy Disk Drives Q1. What type of floppy disk drives are used in the EQUITY I? Can other IBM compatible floppy disk drives be used? A. The following models of half - height, 5.25”, 360KB floppy disk drives have been used. The most common type was the MD- 5201- 55. 1. CANON MDD- 531- 51 2. CANON MD- 5201- 55 3. EPSON SD- 525- 501 Because of the non-standard FDD interface, other floppy disk drives cannot be used. Q2. Can a 3.5”, 720KB or 1.44MB Floppy disk drive be installed? A. No, the Equity I does not support 3.5” floppy drives. Q3. Can a 1.2MB floppy disk drive be installed? A. No, the Equity I does not support 1.2MB floppy disk drives. Q4. What is a “601” error on power - up? A. This is a floppy disk controller (FDC) error caused by an invalid response during the FDC status check. Refer to the Equity I diagnostics manual. It may indicate that the FDD cables are not connected properly or the controller is faulty. PSB No: S-0060A Page: 2 of 8 Q5. Is it possible to disable the Equity I floppy disk controller? A. No. the floppy disk controller cannot be disabled. Hard Disk Drives (See Hardware Update information on page 7) Q6. Does the Equity I have enough power to support 2 floppy disk drives and a hardcard type hard disk drive? A. Yes, although the power supply is rated for 53 watts the Equity I main system board was designed with many low power custom C - MOS components which draw very little current. In order to conserve available power, it is recommended to use a hardcard which draws 12 watts or less. Q7. Is the Plus Development Hardcard 20 compatible with the Equity I? A. Yes, the manual installation procedure in the Plus Development installation instructions must be followed. Q8. Can a hardcard be installed in addition to a hard disk drive? A. No, this is not recommended as it may overload the power supply. Q9. What type of hard disk does Epson supply with the Equity I and what is the average disk access time. A. Epson originally supplied a half - height, 5.25”, 20 MB, Epson model HD- 860 hard disk (89ms) with controller. This drive has since been replaced with the HMD - 720 with an average access time of 69ms. Q10. What hard disk controllers can be used? A. The Western Digital (WD1002A - WX1 or WX2) hard disk controller is recommended for use in the Equity I for MFM type HDDs. Most other IBM PC/XT compatible controllers will also work. PSB No: S-0060A Page: 3 of 8 Q11. Can hard disks from other vendors be used? A. Yes, the customer should purchase a 1/2 height, low power unit such as the HMD- 720 offered by Epson. Q12. Can an EGA or VGA adapter board and monitor be used with the Equity I? What are the dip switch settings for EGA and VGA video mode? A. Yes, but ensure the ROM BIOS is version 2.20 or 2.21 and set the front panel dip switch 1 - 6 and 1 - 7 to “on”. Q13. Some programs requiring Hercules graphics will not display graphics on the monochrome monitor used with the Epson MGA multigraphics adapter. Is there anything to correct this? A. It may require a patch program that has been developed to overcome some compatibility problems that may occur with a few application programs. See PSB# 0024. The patch utility files (PATCH.ARC) can be downloaded from the Epson Product Support RBBS system and from Compuserve's Epson Forum. They are compressed and can be uncompressed with ARC. The Product Support RBBS system can be accessed anytime by remote modem at Tel. (213) 534- 8506. Protocol: no panty, 1 stop bit, 8 data bits, 1200/2400 Baud. Q14. Is the NEC Multisync monitor compatible with the Equity I? A. Yes, with the appropriate EGA video card. Q15. My color monitor display blinks on and off when in 40 column mode using the Epson MRS- CR, CGA color video board. A. This can be corrected by replacing the MRS - CR board with an MGA video board or by modifying the MRS - MT board. The modification consists of cutting the printed circuit between CN1 - B30 and CN2 - B30 and adding a 39 Ohm 1/4 watt resistor in series with the OSC dock to the option slots. PSB No: S-0060A Page: 4 of 8 General Information Q16. What is the latest MS - DOS version available for the Equity I? A. Epson’s MS - DOS 3.2 has been certified for use with the Equity I. It is available from Epson’s Accessories Sales Department at 1-800- 873- 7766. Q17. What is the latest ROM BIOS version for the Equity I? A ROM BIOS version 2.21 (P/N Y144800401). Q18. What kind of memory upgrade is available for the Equity I? A. Epson offers a 384KB RAM board with Real Time Clock and Calendar (part number Q515A - AA). It replaces the MRS - MT expansion slot board and provides 640KB memory. It is available from Epson’s Accessories Sales department. A similar board called the Tahiti Board is available from Image Technology Inc. at Tel. # (383) 799-8433. If the Equity I originally came with 512KB, the 256KB RAM board plugged into the system board next to the floppy disk drive assembly must be removed. Q19. How do you set the Epson 384K RAM Board Real Time Clock, date and time? A. Use the SETRTC utility program supplied with the 384K RTC board. Q20. After installing a 384K RTC board the Equity I will no longer boot What could the problem be? A. Make sure the Epson RTC driver (RTCDEV.SYS) is the first file loaded from the CONFIG.SYS file. Q21. Does The Equity I have panty check for RAM? A. No, the Equity I does not have panty checking capability. PSB No: S-0060A Page: 5 of 8 Q22. Which Math- Coprocessor chip do I need? A. An 8087 Math-Coprocessor chip which runs at 4.77MHz is recommended. Jumper J1 must be removed for 8087 operation. Refer to figure 1 on page 8. Q23. Where is the 8087 socket located? A. The 8087 socket is located on the main system board next to the CPU chip toward the rear of the board. The upper chassis, which holds the power supply and FDD assembly must be removed to install the 8087. Refer to figure 1 on page 8. Q24. Will IBM compiled BASIC programs run on the EQUITY I? A. BASIC programs written for the IBM PC- XT will run as long as they do not require IBM’s BASICA. BASICA is resident in IBM’s copyrighted ROMs. Equity computers. use a version of GW - BASIC which is loaded from diskette. Due to some differences in BASIC, some programs will not operate correctly if they require BASICA. Some applications look for the file name BASICA. Renaming the GW - BASIC file to BASICA can sometimes solve these problems. Q25. I can’t find some of the programs referred to in the MS - DOS manual on the MS - DOS diskette. Where are they? A. The GW - BASIC diskette contains many of the utility programs, such as EDLIN and XTree, which are referred to in the MS - DOS manual. Q26. Can I use a third party type keyboard with the Equity I? A. Yes, except for early production units which do not have any keyboard jumpers on the main logic board. Third - party “enhanced- style” keyboards such as the IBM XT - 101, NorthGate C/T - 101, Datadesk Turbo - 101, Keytronics 101, 5150 and 5151 or the standard PC/XT type 84 - key keyboards can be used. Jumpers must be installed in positions J2 and J3 on the main MRS board. The original keyboard may not be used once the jumpers have been installed. Refer to figure 1 on page 8. PSB No: S-0060A Page: 6 of 8 Q27. Can the Epson Plus series “Enhanced” keyboard be used with the Equity I? A. No, the Epson Enhanced keyboards are not supported. Q28. IS the Equity I compatible with any 286 or 386 accelerator boards? A. Yes, it has been tested with the Sota 286i from Sota Technologies, Tel.# (408) 245- 3366 and the PC Elevator board from Applied Reasoning Corp, (617) 492-0700. It has not been tested with any 386 accelerator boards. Q29. Can the 8088 CPU be replaced with an NEC V20 CPU chip to increase the processing speed? A. Yes, but Epson does not support this configuration. Q30. Is there any upgrade to run copy protected software? A. No, due to the copy protection scheme used on various software programs such as most Electronic Arts game software, they are not compatible with the Equity I. A non - copyprotected version is sometimes available from the manufacturer. Q31. Can BACKUP and RESTORE be used to copy files over to an Equity I hard disk from another system? A. Only if the Equity I is using MS - DOS version 3.2. not supported with MS - DOS 3.1 or earlier. BACKUP and RESTORE was Q32. What streamer tape drives can I use for high speed backup? A. The Equity I is compatible with most IBM PC/XT streamer tape backup units. Q33. Will the Equity I work in foreign countries? A. Yes, the Equity I computer can be used internationally by using a 220 VAC to 110 VAC voltage stepdown transformer.

Product Support Bulletin Subject: Using Expanded Memory with Equity and Apex Computers Date: Page: 3/2/90 1 of 6 Q1. A. Q2. A. PSB No: Originator: S-0047C KAS ‘/“p& What is Expanded Memory? Conventional memory, managed by MS - DOS, is limited to 640K. In response to the need for greater amounts of accessible memory, the LIM EMS (Lotus/Intel/Microsoft Expanded Memory Specification) was introduced in 1984. EMS, version 3.2, provides usable memory beyond the 640K limit through “bank switching”. The expanded memory is divided into 16K portions called “pages”. The computer accesses these pages through a “page frame” or “window” which is 64K of memory located between 768K and 896K in 80286 - based systems and between 800K and 960K in 8086 - or 8088 - based systems. 16K pages of memory are allocated for an application’s use and the EMM (Expanded Memory Manager) handles the job of mapping the pages in and out of the page frame as they are needed. However, in order to make use of expanded memory, the software must be written to take advantage of the EMS. Software such as Lotus 1 - 2 - 3, Microsoft Windows and Borland’s SideKick Plus make use of expanded memory. EMS is limited to 8Mb of expanded memory. What is EEMS? A superset of EMS, AQA EEMS (AST/Quadram/Ashton - Tate Enhanced Expanded Memory Specification) provides greater flexibility in the mapping of expanded memory. However, it also uses the technique of “bank switching” and has its own memory manager which accommodates such specially written software as Quarterdeck’s DESQview. EEMS is also limited to 8Mb of expanded memory. PSB No: S-0047C Page: 2 of 6 Q3. A. Q4. A. Q5. A. What about the 155Mb RAM listed as the maximum for the Equity III +? This larger amount of RAM is the maximum usable memory range for an 80286 microprocessor and generally refers to extended memory. Extended memory starts at the 1Mb boundary and extends out to 16Mb. As it requires a 24 - bit address to access memory in this range, extended memory is handled by the protected mode of the 80286. Examples of currently available software that can switch into protected mode to use extended memory are Framework II, AutoCAD, the VDisk RAM disk and Xenix OS. How does LIM EMS 4.0, the latest version, differ from the earlier version, LIM EMS 3.2? EMS 4.0 supports up to 32Mb of expanded memory where EMS 3.2 supported only 8Mb. EMS 4.0 has been changed to make it easier for applications to share expanded memory. In EMS 4.0, page mapping has been streamlined and new functions allow application programs to dynamically increase and decrease the amount of expanded memory allocated to them. In previous versions of EMS, the page frame was located in an unused 64K block of memory between 640K and 1Mb. EMS 4.0, subject to limitations in the system hardware, supports the page frame anywhere in the first 1Mb of memory. Before EMS 4.0, the page frame held four pages. Now you can define a page frame of up to eight pages in memory above 640K. The size of the page frame is limited only by the amount of available memory. There has also been a change to support the smaller than standard (16K) memory pages used by some expanded memory boards. Is EMS 4.0 compatible with my old expanded memory board? The EMM 4.0 driver works with existing hardware. You don’t need to buy a new expanded memory board. However, until you use applications that have been written to take advantage of EMS 4.0, you probably won’t notice much improvement in performance over your older version.

They have been removed from the list because Micron no longer produces ISA memory boards. Q12. A. How do you expand the memory of the Equity 386/20? Memory expansion in the Equity 386/20 can be accomplished by adding SlMMs (single in - line memory modules) to the CHET - RM board. Both 256K and 1Mb SlMMs are available from Epson America. The 256K SlMMs are sold in 1Mb kits and the 1Mb SlMMs are sold in 2Mb kits. Compatible third party 1Mb SlMMs are available from Matsushita, Toshiba and CDC Enterprises. You can also use third party memory expansion boards such as those listed above for the Equity II +/Ill +. PSB No: S-0047C 5 of 6 Page: Q13. A. Are there any guidelines to installing the SlMMs in the Equity 386/20? Yes, when SlMMs are installed to increase memory beyond 1Mb, they must be installed so that banks of SlMMs are installed as matched pairs. See the matrix below: Memory Bank 0 1MB 2MB 4MB 4MB 8MB 10MB 16MB 4X256KB 4X256KB 4X256KB 4X1MB 4X1 MB 4X1 MB 4X1 MB Note: Bank 1 Bank 2 Bank 3 4X256KB 4X256KB 4X256KB 4X256KB 4X1 MB 4X1 MB 4X1 MB 4X256KB 4X256KB 4X1 MB 4X1 MB Refer to PSB S - 0095 for 18MB RAM Setup information. Q14. Is there a driver supplied with the Equity 386/20 to allow the use of the extended memory as expanded memory? A. Yes, the Equity 386/20 system software includes the device driver EEMM386EXE. This driver emulates LIM EMS 4.0 memory using the extended memory supplied by the additional SIMMs. It will support only the onboard memory above 1 MB, up to 15MB. This is the maximum memory that can be installed on the CHET- RM board. It will not support memory installed on memory expansion boards. Q15. Are there any expanded memory boards that are compatible with the Equity LT? A. No, the option slots on the LT require a special connector. The hard drive controller and the LT cartridge modem are the only option cards currently available from Epson America. Q16. What expanded memory boards are compatible with the Apex by Epson? A. The Above Board PC from Intel Corporation has been tested by Epson in the Apex. PSB No: S-0047C Page: 6 of 6 Q17. Are there any general guidelines for determining the chip speed to install on the memory expansion boards? A. Yes, if the CPU speed is 8MHz or less, use 150ns RAM chips. If the CPU speed is 10/12MHz, use 120ns RAM chips. Q18. Is there anything that should be kept in mind during the installation procedure for the memory expansion boards? A. Yes, when installing the memory boards in the Equity II + and Equity Ill + (12MHz models), remember that the bus speed is 12MHz. For example, the Intel Above Board 288 and Above Board Plus allow you to set up the bus speed and chip speed in their installation programs. Q19. What is meant by backfilling memory when using software such as DESQview? A. Backfilling is a function of many expanded memory boards which allows a portion of the board’s memory to be used as conventional memory. In this way, you could turn a 256K system into one with 840K memory or more. In certain situations, you may want to disable some of the computer’s conventional memory and the use the memory on the expansion board (i.e. DESQview). Q20. Which Epson computers have memory settings that allow backfilling memory? A. The Equity I, Equity I +, Equity II + and Equity Ill + allow backfill. The Equity I comes with 256K standard and the Apex comes with 512K, thus allowing backfill. The Equity I + has DIP switch settings allowing system memory to be disabled to 256K or 512K. The Equity II+ and Equity Ill + have jumpers on the system memory boards to allow memory to be disabled to 256K and 512K. EPSON EPSON AMERICA INC.

A single line of text may take up to a minute to print. (serial output) Word uses BIOS interrupt 14h function 1 (send character to port) for driving either COM port. The function number is placed in the AH register and the interrupt called. On return, AH is supposed to contain the line control status. However, AH is still set to 1, indicating that a character is ready to be received. Word then calls interrupt 14h, function 2 (receive character) and attempts to receive the character. After 1 to 2 seconds, the routine times out and transmission is resumed. There are three methods of correcting this situation: 1) If the printer supports hardware handshaking, redirect the printer output (MODE LPT1:=COM1:) and configure Word for LPT1. This works reliably with Epson printers or similar devices. 2) Epson has developed a patch program (SERFIX.COM). This is a TSR that insures that proper status is returned from INT 14h, function 1. This program is CompuServe (Epson and Microsoft available from Forums) and the Product Support Center BBS. 3) A revised ROM BIOS has been developed for 'the above systems. This is a limited release and will only be supplied on an as-needed basis. Method 1 is the easiest solution. Method 2 is effective and is recommended for individual users.

The modified MODE utility will fix this problem. It will work exactly the same as the normal MODE utility in all situations, even when the IBM EGA adapter (or equivalent) is not installed. MODEHERC.COM - RAM-resident utility which allows the use of Hercules monochrome graphics. MODEHERC.COM allows programs such as Lotus 123 release 1A to use Hercules emulation on the Equity II. These programs require that you run the Hercules utility HGC.COM (usually HGC FULL) to be able to utilize graphics. SuperCalc 3 exhibits a different problem. It will display one graph successfully, then subsequent graphic displays will be garbled. MODEHERC.COM will also fix this problem. Since MODEHERC.COM remains resident in memory, it only needs to be run once. It is recommended that MODEHERC.COM be the last memory resident program loaded on the system. For example, if you will be using Sidekick, run MODEHERC after Sidekick has been loaded into memory.

The device driver EQRAMDVR.SYS provides the support needed for these utilities by creating an 'empty' disk drive that a RAM disk program can use when it is executed. HOW TO USE EQRAMDVR.SYS Since EQRAMDVR.SYS is a device driver, it must be specified in See pages 3-1 to 3-4 in the CONFIG.SYS file on your boot disk.

SERVICE DEPARTMENT SUPPORT PRODUCT 6/8/87 DATE: EPSON SUBJECT: EQUITY ENHANCED KEYBOARD NUMBER: COMPATIBILITY S-0012 The purpose of this bulletin is to provide information regarding style Equity Plus series the compatibility of the enhanced "AT" keyboard with the Equity family of computers and a general statement on software support. With the introduction of the Equity It and III+, Epson brought out an enhanced keyboard design - very similar to the enhanced keyboard introduced by IBM on the Model 339 AT. There are a couple of areas to make note of. 1. Keyboard Compatibility The enhanced keyboard cannot be used on an Equity -‘I, II or III. The enhanced keyboard (as with IBM's) requires explicit ROM BIOS support. The Equity It and Equity III+ incorporate this support; the earlier machines do not. It is possible, however, to use a third-party "enhanced-style" keyboard (such as the Datadesk Turbo-101) which offers switch selection for PC/XT or AT usage. (Please note that early versions of the Equity I and II did not support any third party keyboards.) The correct jumper Equity I: Equity II: settings for non-Epson keyboards are: J2 and J3 jumpered J 3 , J4 and J5 set for position 1 Also note that once the above jumper changes have been made, attempting to use the Epson keyboard will result in damage to the keyboard-and main board. 2. Software Compatibility Not all applications "know" about the enhanced keyboard. The and mapping are subtly different. If you experience scan codes difficulties with certain applications (particularly any that re-program the keyboard), contact the software vendor and ask about enhanced keyboard support.

However, method can used with just ‘the systems software as provided with each machine. 1. Before physically installing the drive, either copy the information from the defect list on the top of the drive or make sure that you have the copy that was included with the drive. What you'll be needing is the cylinder/head information - you don't need the byte location. 2. Verify that the terminating resistor pack is installed and that the drive select jumper or switch is correctly set. The drive should be selected as the lowest number - i.e., DS0 assuming a range of DS0-DS3. 3. Some drive manufacturers do the physical or "low-level" format at the factory. DON'T ASSUME THIS! One indication is this: start the HDFMTALL program. If the cylinder count-down goes quickly (approx. 1 sec. per cylinder), then the physical format is very likely sound. If longer than this, it takes other measures are called for. Re-boot the system and proceed to step 4. 4. Invoke the DEBUG program. At the dash (-) prompt, enter: g=c800:5 and press ENTER. At this point, DEBUG executes (Goes to) the instructions at hex address c800, offset 0005. This is the ROM BIOS on the HD controller card. Stored at this address is the physical formatting routine provided by the controller manufacturer: You may encounter two types: Western Digital or National Computer Labs (NCL). The Western Digital is the simpler of the two. It presents you with information about how the drive number and interleave factor are stored in the AX register and prompts "Press y to begin formatting drive C with interleave 03". Press any key other than "y" and it aborts. If you enter "y", it IMMEDIATELY proceeds with the format. DON'T PRESS "Y" UNLESS YOU REALLY MEAN IT! It will then inform you when the format is complete and return you to the A prompt. Page 1 of 2 somewhat more complicated. It will ask you format is The NCL for drive number (0), number of cylinders (615), number of reduced write current (615), write precompensation heads (4), length (11). The maximum ECC data error burst (615) and parentheses would be typical for the given here in numbers all is correct; if yes, it HMD-720-802. It will then ask if it returns you to the top of proceeds with the format. If not, format, it the input menu. In any case, when it completes the you wish to enter alternate track selections. you if may ask Tell it "no". 5. . Invoke the program HDFMTALL. This program will allow you to table, which we just knocked out reconstruct the bad track with the physical format. HDFMTALL will ask if y o u want a "standard" format; press "N". It will then ask if you want the you can accept this or change it. default interleave of 3; (I've found that an interleave of 6 seems to be pretty optimal on the I and II.) HDFMTALL will then display the bad track table and give you the chance to edit it. If any bad tracks are displayed, make sure that any bad locations from the error list you took off of the drive are indeed flagged. If not, enter them manually. If the scan turned up an excessive (more than 50) number of bad tracks, you might want to delete them and then manually enter the ones from the error list. Press "F" when you are finished and HDFMTALL will proceed with the warnings and then the actual format. 6. You're now ready to use HDPART. This program sets up the MS-DOS partition and writes the DOS file structure to the disk. Typically' you'll use the entire disk for DOS, so that simplifies matters. Just make sure that the DOS partition is specified as BOOTABLE. When y o u exit HDPART, the system automatically re-boots. 7. The final step - HDFORMAT. From the A prompt, enter the following: The /S switch transfers the HDFORMAT C: /s/v. operating system to the hard drive. The /V switch causes HDFORMAT to prompt you for a volume name for drive C. HDFORMAT now performs the logical format. When finished' remove the floppy from drive A and press CTRL-ALT-DEL. The system should boot from the C drive. For those of you familiar with the IBM world, the DEBUG format is the same. HDFMTALL is the equivalent to IBM's Diagnostics level format; HDPART is our version of FDISK, and HDFORMAT is the same as IBM's FORMAT. Page 2 of 2 E P S O N EPSON AMERICA INC.

At that time the Equity I ROM BIOS was also updated to MSA-B4 to support the step rate of the new floppy drives. The MS-DOS 2.11 version software should be used with the MSA-B4 Equity I ROM BIOS. This new software package is with the "S1" product code. already included in Equity I boxes If you currently have Q595A-AA software packages in your inventory, they should only be used to replace software in Equity I units not having the product code (units with serial " S1 " numbers below 080001), unless they are being retrofitted with the MD-5201-55 floppy drives. In that case the ROM BIOS must also be updated. The new MS-DOS 2.11 software and new ROM BIOS have no other functional differences from the previous version other than compatibility to the MD-5201-55 floppy disk drive.

Because of certain file name differences between Epson's MS-DOS and IBM's PC-DOS, the Plus install program will not run using Equity MS-DOS. Unfortunately, Plus Development does not officially support the use of the HardCard in the Equity computer series, because it has not been formally tested and approved by Plus Development. It has, however, been tested and officially approved by Epson's Vendor support staff. The HardCard is shipped in a partitioned and formatted state, with a number of files included on it. The directory of files is as follows: INSTALL HCD HCD1 HCD2 HCD3 HCD3 HCD6 PREPARE SHELL LIGHT SOUND PATCHFMT INSTALL EXE BAT BAT EXE DAT DIF SCR BAT BAT COM COM EXE DAT 47479 30 128 54769 13440 704 4224 235 18 145 145 12670 425 1-01-80 1-01-80 1-01-80 1-01-80 1-01-80 1-01-80 1-01-80 1-01-80 1-01-80 1-01-80 1-01-80 1-01-80 1-01-80 12:06a 12:07a 12:07a 12:07a 12:07a 12:07a 12:07a 12:08a 12:07a 12:07a 12:07a 12:08a 12:06a Page 1 of 3 installation routine (INSTALL.EXE, files comprise the These INSTALL.DAT, PATCHFMT.EXE, PREPARE.BAT, and SHELL.BAT), the Plus fixed disk menu program (HCD*.*), and supplemental Development utilities (LIGHT.COM and SOUND.COM).

For Equity "power users" who are comfortable with MS-DOS, and who don't wish to use the Plus-supplied menu program, they can set up the HardCard by simply copying files to a formatted the Plus floppy diskette, and then using HDPART and HDFORMAT in the normal fashion (Equity II users should run SETUP.COM first to make sure that drive C: is properly specified - for the HardCard, it should be set as "Not installed or other"). Users may want to copy the LIGHT.COM and SOUND.COM utilities back to the HardCard, as these files control visual and audible signals that are used to indicate HardCard access. The visual indicator is a flashing "+" sign at the upper right of the display (defaults to ON), and the audible indicator is a buzzing sound (defaults to OFF). However, if the user would like to set up the HardCard as though the Plus installation was (i.e. complete with their "shell"), performed then they should manually duplicate the Plus routine, as detailed in the following section. This procedure was outlined by the Plus Development technical staff, and I have substituted the alternate commands that the Equity MS-DOS uses. Note that, while some of the steps seem redundant, the procedure was designed so that disk swapping on a single floppy system would be minimized, and also for automatic operation.
