SUBJECT: EPSON EQUITY I/II/III ENHANCED KEYBOARD COMPATIBILITY
The purpose of this bulletin is
to provide information regarding
the compatibility of third party enhanced "AT" style keyboards
with the Equity I, Equity II and Equity III computers.
1. Keyboard Compatibility
The enhanced Equity "Plus" series keyboard cannot be used on an
Equity I, II or
III.
The enhanced Equity keyboard (as with
IBM's)
requires explicit ROM BIOS support
which is not
available in the earlier machines.
It is possible, however, to use a third-party "enhanced-style"
keyboard such as the
IBM XT-101,
NorthGate C/T-101, Datadesk
Turbo-101,
Keytronics
101,
5150
and
5151. Please note that
early versions of the Equity I (serial numbers unavailable) and
Equity II
(below
serial
number
29875) were not designed to
support
any
third
party
keyboards (they do not have any
keyboard-select jumpers on the main board).
The correct jumper settings for non-Epson keyboards are:
Equity
I:
J2
and
J3
jumpered
Equity
II:
J3,
J4
and J5 set for position
1
PLEASE NOTE
Once the above jumper changes
have been made, attempting to
use the original Epson keyboard
will result in damage to the
keyboard and Equity main board.
