The SS-3004 MEMO PROCESSOR with Data Communication Solid State Software Cartridge (SSSC) was developed by Texas Instruments for its CC-40 Compact Computer System and transforms it into a portable, powerful word processor and data communications terminal.

Don't miss an early prototype of the SS-3004 SSSC with a "DATA COMMUNICATION" label instead od the final "MEMO PROCESSOR" wording.

The word processing portion of Memo Processor allows to create, print and store documents using the following features:

Up to 32 tab stops
Line length variable from 9 to 80 characters
Automatic word wrap at end of lines
Automatic page size control
Insertion, deletion, and overstrike of characters
Rearrange text using block move, copy, and delete functions
Search function allows location of character strings
Document printing on all CC-40 compatible printers

The communications portion of Memo Processor allows the CC-40 to access computers such as:

Central timesharing systems including TEXNET
Corporate computers
Personal computers

Dismantling this Solid State Software Cartridge manufactured in March 1984 by Texas Instruments in their Lubbock, Texas facility, reveals a small printed circuit board (PCB) with a HN61256P ROM (Read-Only Memory) manufactured by Hitachi, Japan.

The HN61256P uses a CMOS process resulting in a very low power consumption of 7.5 mW and features a capacity of 32k Bytes with an access time of 3.5 us.
