Subject: Proper Method for Running Benchmark and Diagnostics Programs

EPSON

Date: 06/04/93
Page(s): 1 of 1

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’ ­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.

in other words, one with no CONFIG.SYS or AUTOEXEC.BAT files.

The Equity I was found compatible with the OmniBridge
controller. It was able to support one or two external
disk drives (daisychained) together. The external drives
could be used as high density (1.2M and 1.44M) or
normal (360K and 720K) disk drives.

The Equity II was found to be totally incompatible with
the OmniBridge controller.

Apex / Apex Plus / Equity Series Keyboards

PSB No: S-0080
Originator: REM

AL

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.
