Control PCB assembly
Original version:
CPU(IC201):
Toshiba TMP90C141N (CMOS) is the 8-bit microprocessor
ROM (IC203):
512K bit or 1M bit EP ROM from SGS, Sony, National
Semiconductor, etc.
The ROM capacity depends on the spelling check function and on
differences in the keyboard arrangements.
4M bit mask ROM can also be used (contains the spelling check
program and dictionary).
ROM (IC204):
2M bit mask ROM (contains the spelling check dictionary).
Gate array (IC202):
The NEC uPD65006CW-A19 or uPD65006CW-A22 is a
semi-custom CMOS gate array in which each gate has been
designed for this typewriter.
RAM (IC205):
256K bit or 1M bit CMOS static RAM (manufactured by NEC and
others), or equivalent.
2nd (second) version:
CPU(IC201):
NEC UPD78F1174 or UPD78F1178 is the 16-bit microprocessor.
The CPU builds in FROM and RAM.
The program is written in at FROM and memory does the store in
RAM.
UPD78F1174: 128K byte-FROM, 8K byte-RAM
UPD78F1178: 512K byte-FROM, 30Kbyte-RAM
RAM (IC203):
128K bit CMOS static RAM (manufactured by Renesas and others),
or equivalent.
