 |
|
MITS Altair 8800 first edition, 1975
The computer is very early:
Original computer comes with two card by default: CPU card rev 0 and Memory card rev 0. That is the MITS basic configuration for most early original Altair 8800 computer.
Look at the second board behind the cpu board. The memory board use gray trace intel memory chip. This memory board alone with CPU board is an very very early one.
