The GE-400 series were time-sharing Information Systems computers by General Electric introduced in 1964 and shipped until 1968.
[2] GE-400 systems had a word length of 24 bits which could contain binary data, four six-bit BCD characters, three eight-bit (ASCII) characters or four signed decimal digits.
These timesharing computers had a Datanet-30 front end to provide the communications capability at 110 baud originally (10 CPS) and later, with a later hardware upgrade, to handle 300 baud (30 CPS).
The GE 412 (1962)[3] was an incompatible computer system with a 20-bit word length intended for process control applications.
[4] GE-400 systems featured a "variable length, relocatable accumulator"[5] which could be set programmatically to a length of one to four words and relocated to overlay any four adjacent locations in memory (modulo four).
