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.

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.

These settings select NO ADDRESS for the OmniBridge BIOS and allow it to coexist with the internal FDC of the computer in which it is being installed.

This way you do not need to disable the internal

FDC or connect any cables from the OmniBridge to internal floppy drives. This was found to be a universal setting for all of the computers listed above as compatible with the OmniBridge controller.


Subject: Tape Backup System Test Results

Date: 6/13/89

Page: 1 of 2

PSB No: S-0087

Originator: MWT w

The Epson America Product Support Center has recently tested four tape backup systems:

Archive VP - 150i

Mountain Series 4000 FileSafe

Tallgrass TG - 4060 +

Tecmar QT - 60e

Internal, 150MB

External, 40MB

External, 60MB

External, 60MB

The tape drives were tested on a variety of systems (please see the notes below). In all cases, the drive manufacturer’s documentation was used as a guide to installation and operation. Note that for 8086/88 computers, the

XT- type settings were used. For the 80286/386 computers, the AT- type settings were used. This is important for correctly configuring the host adapters or controller cards for IRQ, DMA and I/O port address.

Archive VP - 150i

The VP - 150i was tested on the Equity II +, Ill + and 386/20. Due to the capacity and nature of the drive, it is not particularly suited for use in any of the 8086/88 computers. This was the only drive supplied with Unix/Xenix device drivers. It was tested under MS -

DOS 3.3 and SC0 Xenix 286 System V version 2.2.1 with no problems encountered. The VP - 150i is also Novell tested and certified under the NetWare operating system.

Mountain Series 4000 FileSafe

The Series 4000 FileSafe was tested on the Equity II+, III + and

386/20. Due to the use of a 16 - bit controller, it was not tested in any of the 8086/88 computers. It was tested under MS - DOS

3.3 with no problems encountered. A chapter is included in the tape software documentation on backup and restore operations on a local area network, including Novell.

PSB No: S-0087

Page: 2 of 2

Tallgrass TG - 4060 +

The TG- 4060+ was tested on the Apex, Apex +, Equity I +,

II +, Ill + and 386/20. It was tested under MS- DOS 3.2 and 3.3

with no problems encountered. There is no documentation on LAN operations.

Tecmar QT - 60e

The QT- 60e was tested on the Equity I +, II + , III + and 386/20.

Testing was conducted under MS - DOS 3.3 with no problems encountered. The Tecmar documentation includes extensive information on installation and operation in a LAN environment.

General Notes

Of the four units tested, the Archive and Tecmar drives offered the easiest installation. They also provided the best performance, with the Tallgrass drive giving the slowest disk-to-tape and tape to- disk operations. All four drives were supplied with menudriven tape utility software for the MS - DOS environment.

Command-line and timed, scheduled operations are also available. As previously mentioned, the Archive drive also included device drivers for use in a Unix/Xenix environment, offering the greatest level of flexibility.

Please contact the manufacturers for additional information.

Subject: Apex / Apex Plus / Equity Series Keyboards

Date: 4/19/89

Page: 1 of 1

PSB No: S-0080

Originator: REMAL

The purpose of this bulletin is to provide information on the various keyboards used with the Apex, Apex Plus and Equity series computers and the part numbers of the keyboard subassemblies used with these keyboards.

The Apex and Apex Plus computer keyboards are to be replaced as whole units.

The Equity series keyboards are repaired to the subassembly level.

The

Equity III keyboard PCB assembly is the only one that comes with the key top set attached.

Since some of the keyboards have the same model numbers, the difference can be determined by the FCC ID number in those cases.

The chart below provides a quick reference to determine the part number of the main keyboard PCB assembly, key top set, control logic subassembly, and keyboard cable.

Subject: Installing a 3.5” 720KB FDD in the Apex Plus

Date: 4/19/89

Page: 1 of 1

PSB No: S- 0079

Originator: REM&

The newer version of the Apex Plus User’s Guide states that the 3.5", 720KB

FDD is not supported however, the system has been tested with and does support the Epson 3.5", 720KB drive (Model Code A112A - AA).

Installing the 3.5” 720KB drive as drive B:

Ensure the Drive Select jumper on the 3.5” FDD is set to DS1. Replace the lower floppy drive with the -new 3.5” FDD. If the new FDD does not slide easily into the lower drive slot, then the top drive and the FDD chassis will have to be removed. The FDD chassis is held in with 1 screw on each side of the chassis at the front behind the front panel. After these 2 screws are removed, the disk drive chassis can be removed be lifting up and forward out of the retaining slots at the bottom.

The 3.5” FDD can then be installed in the lower position and the FDD chassis can then be reinstalled in the computer.

The top 5.25” FDD can then be installed and the system booted up with MS-

DOS. In order for the system to recognize the B: drive as a 3.5”, 720KB FDD, a CONFIG.SYS file with the following statement must be created or added to the existing CONFIG.SYS file:

DRIVPARM = /D:1/F:2

Installing the 3.5” 720KB drive as drive A:

If installing the 3.5” 720 as drive A: it must first be installed as drive B: and a 3.5” MS- DOS system disk must be created.

Boot the system with the

MS - DOS system disk in drive A:.

Insert a blank 3.5” diskette in drive B then use FORMAT B:/S to format and copy the system files to the 3.5” diskette.

Use COPY A:*.* B: to copy all the other MS - DOS files from the 5.25” diskette to the 3.5” diskette.

In order for the system to recognize the A: drive as a

3.5”, 720KB FDD, a CONFIG.SYS file with the following statement must be made or added to the existing CONFIG.SYS file:

DRIVPARM = /D:0/F:2

There are no dip switches or jumpers to change on the computer, but the drive select jumper on both floppy disk drives must be set to DS1.

The 5.25” FDD can then be installed as the lower B: drive and the 3.5” FDD can be installed as drive A:.

SUBJECT: APEX PLUS - GW-BASIC 3.2 UPDATE FOR HERCULES GRAPHICS

The purpose of this bulletin is to provide information on a solution to a problem using GW-BASIC in Hercules Graphics mode with the Apex Plus computer.

Epson GW-BASIC 3.2 (version 1.04) and the multimode video graphics adapter in the Apex Plus support Hercules Graphics.

However, when using the Epson GW-BASIC 3.2 (version 1.04) for

Hercules Graphics it will not work with the Apex Plus except in the following cases:

1.

When a different Hercules Graphics board is used.

2.

After enabling the Hercules mode by using another application. ie: by displaying a graph in PFS First

Choice then exiting First Choice and loading GW-BASIC.

This is caused by the video board check routine in the

GW-BASIC software which mistakingly determines that the video board is MDA.

If the Hercules mode is used by another application, it will enable the video board Hercules Graphics mode.
