Apex Plus; Apex; Psb No: S-0111 - Epson Equity II Product Support Bulletin

Subject: Apex / Apex Plus / Equity Series Keyboards
Date: 4/19/89
Page: 1 of 1
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.
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.
