The PB 250 (later Raytheon 250[1]) was a general-purpose computer introduced in 1960 by the Packard Bell Computer Corporation.[2][3]
Central Computer weighed 110 pounds (50 kg).[4][5][6]
Design
Design started in November 1959. Computer was intended as a component in special purpose systems.[2]
Logic design has similarities with Bendix G-15 computer, which in turn was based on Alan Turing’s Pilot ACE.[7][8][9]
Circuits were derived from TRICE[10] digital differential analyzer.[4][11]
People involved in development:
- Max Palevsky - general manager, started the development process.[8]
- Stanley Frankel - consultant on the design of the computer logic
- Robert Beck - designer of the computer logic[8][9]
- Smil Ruhman - circuit design
- Jack Mitchell and Donald Cooper - management and coordination of the overall engineering project[12]
Features
Used Flexowriter as console.[13][14][15]
Could be operated entirely from a battery power supply.[4][16][17]
Software
- SNAP I (Symbolic Non-optimizing Assembly Program) assembler[18]
- ATRAN (Algebraic TRANslator), process oriented language[19]
- CINCH Interpreter, a floating point interpretive system, designed to permit rapid programming of scientific and engineering problems.[4][20]
- OUP III (Octal Utility Package III)[21] which "allowed the operator to perform certain transfer functions, printout locations of memory, store single words into memory, and begin the execution of programs that had been stored in memory."[1]
- NELIAC compiler[22]
- Fortran II[23]
Uses
By WANEF (Westinghouse Astronuclear Experiment Facility), whose task was to perform basic research and reactor analysis on the NRX series of nuclear reactors to be used in nuclear rocket engine.[24]
In Saturn 1 first stage checkout.[1]
In TRICE models TC5108/250 and TC5036/250[25] hybrid computers.
In Hycomp 250 hybrid computer, later replaced by PB440.[26]
In nuclear submarine training systems[27] and in antisubmarine warfare trainers.[28]
PB 250 was licensed to SETI (French: Société européenne de traitement de l'information, lit. 'European Information Processing Company').[29] It could be connected to SETI 2000 process control system.[14]
In mobile (by van) monitoring and data processing services.[30][31][32]

For applications where power failures and resultant loss of memory cannot be tolerated a battery power supply is available which will operate the computer for several hours without line power.

A battery-operated electronic computer, PB 250, has been shown by Packard Bell Computer Div., Packard Bell Electronics. In normal operation, it operates from a battery trickle charged from a 115-v. power line. If 115-v. input is interrupted, computer can continue operating for more than 1 hr.

For the first time, we believe, an electronic computer can operate entirely from a battery power supply.
