2650 Mark I (continued)

A photo taken in March 1979 of the personal computer that I designed and built derived from the April through June Radio-Electronics magazine articles.

This is an overhead photo of the computer. The power supply is on the right, the S-100 boards (a standard board of the time that had 100 contacts on its edge connector) are the long ones towards the top of the photo and there are a couple of Radio Shack 4.25” 44-pin boards in the foreground. The ribbon cables coming from one of them connect to the keyboard and to the cassette tape recorder.
