Transistor computers • Early transistor computers: • FACOM 222 • FACOM 231 • FACOM 230 series: • FACOM 230 / FACOM 230-30 • FONTAC / FACOM 230-50 • FACOM 230-10 • FACOM 230-60 (1968) • FACOM 230-5 series • FACOM 230-25, FACOM 230-35, FACOM 230-45 (1968) • FACOM 230-45S, FACOM 230-55 (1974) • FACOM 230-75 • FACOM 230-75 APU (1977) - A computer for scientific and technological calculations with enhanced computing power by adding a pipeline system "array processor" (
vector processor) to FACOM 230-75. FACOM 230-75 APU achieved 22M FLOPS. It was delivered to the National Aerospace Laboratory of Japan (
JAXA). It's only one year behind the Cray-1. This machine will lead to the later VP series. • FACOM 270 series: • FACOM M series: IBM System/360, System/370 compatible • FACOM M-190 (1974): This is a super-large machine that uses LSI, and has two to three times the performance of IBM System/370. The fastest computer in the world at this time. • FACOM M-200 (1978): The fastest computer in the world at this time. • FACOM M-130F, M-140F, M-150F, M-160F, M-170F (1979): Supports
Japanese language. Includes software supporting Japanese, a device for inputting Japanese, and a
Kanji dot impact printer. • FACOM M-380, M-382 (1981): Supports 31-bit address space (2GB). A super-large machine that uses ECL / TTL LSI. • FACOM M-780 (1985): A super-large machine that uses an ECL LSI with 10,000 gates / chip. Maximum physical memory 256 Mbytes, maximum 64 channels. Water cooling.
