The Intellec computers were a series of early microcomputersIntel produced in the 1970s as a development platform for their processors.[1] The Intellec computers were among the first microcomputers ever sold, predating the Altair 8800 by at least two years.[2]

Intel Intellec 4 Mod 40
Also known as
Intellec 4 Mod 40, Intellec 8 Mod 80, Intellec MCS4/MCS8
The first series of Intellecs included the Intellec 4 for the 4004, the Intellec 4 Mod 40 for the 4040, the Intellec 8 for the 8008, and the Intellec 8 Mod 80 for the 8080.[2]
The Intellec 4 and 8 were introduced at the June 1973 National Computer Conference in the New York Coliseum.[3] The Intellec computers were sold not to the general public, only to developers, and a very limited number were built. The Intellec 8 retailed for $2,395.[2]
Features
The Intellecs have resident monitors stored in ROMs.[3] They also included an assembler, linker, and debugger, as well as the ability to act as an in-circuit emulator.[4] Additionally, a PL/M compiler, cross-assembler and simulator were available, which allowed writing programs in a higher-level language than assembly. FORTRAN compilers were also available.[5] The Intellec 8 supported a Teletype operating at 110 baud, a high speed punched paper tape reader[6] and a CRTterminal at 1200 baud.[7]
The Intellec 8 is able to address up to 16K of memory and came with 5K pre-installed. The Intellec 4 came with 1K of PROM and 4k of RAM for instruction memory, as well as 320 4-bit words of data memory, expandable to 2560 words. The Intellec 8 ran with a two-phase clock of 800kHz, resulting in an instruction cycle time of 12.5us. The Intellec 4 ran at a slower clock rate of 750kHz, but had a faster instruction cycle time of 10.8us. Both systems were available in "Bare Bones" editions, which omitted the front panel, power supply, and completed chassis; instead, it is designed to mount into a rack. Both systems also weighed 14 kilograms (31 lb).[5]
