Intel Intellec 8 MCS 8080 1973 Computer Running

Hi there, this is a short video of my old Intel Intellec 8 computer running. Released in 1973 the computer is based on the 8080 8 bit CPU, would have originally used paper tape to store programs and a teletyper to access it.

i love vintage computers. i cant stand new technology. i just cant.

What did it actually do?

If you ever do this video over would you please give some more light to the view. Nice to see it working after 1973.

@HondaH100A and Jerkwad152:

Chronology: 4004, 8008, 4040, 8080, 8085, 8086, 8088, etc

Both 8080 and 8085 had simple 16-bit instructions. The difference is that the 8085 was electrically more modern + a few minor fixes. Both had external 16-bit address and 8-bit data buses.

The 8086 / 8088 had a full set of 16-bit instructions and a 20-bit address bus (1MB). The 8086 had a full 16-bit external data bus, while the 8088-variant had an 8-bit external databus (but 16-bit internally).

@HondaH100A Actually, the 8085 came after the 8080. It was also an 8-bit processor, but capable of very limited 16-bit instructions. Intel didn't get much use out of it, since the 8086 came out soon after.

@OBSysteme

Thanks for the advice, i will defo look that up.

This was one of several machines built by Intel for verifying the design of hardware and software for the 8080 microprocessor. A socket on the front of the machine can be used to program an EPROM or run an application from one. These things are exceedingly rare; they were only built on request.

I'd love to have one of these, if only a company still made them in kit form.

From what I have read, the 8008 would have been the first CPU, but was released after the 4004 in March '73. The 8080 was developed in April '74, but wasn't marketed until '76. It was used in the Altair 8800 in '76. This being the first personal computer. The 8086 came next and looks similar to the 8080, but the 8086 had a 16-bit data path rather the 8-bit data path that the 8080 had. Both had a 16-bit address bus. The computer in the video is a 8008 going by the year.

Wow. Like a seventies time warp. The 8080 was the cpu that created a market for the microprocessor. It was used in the Altair 8800 - the first personal computer.

The 8080 has a 16 bit address bus and a 8 bit data path. The 8086 had a 16 bit data path and ran between 4-10 mhz. The 4004 and the 8008 that were introduced before the 8080, were the very beginings of the Intel cpu world.
