Here is a link to the Nascom schematics again as a reference.

At this point, when I build the boards below, my Nascom still existed as the original board. The board was roughly the size of a DIN A4 sheet of paper. With the help of the Z80 buffer and the parallel bus cards shown here, I was able to move the Nascom piece by piece to a card system consisting of a couple of 100x160mm cards.

Emptying the Basement: My Computer History

I’ve started the process of emptying my basement. There is still stuff there, that I’ve build during my apprenticeship years with the company then called “Nixdorf Computers”, basically my computer roots from more than 30 years ago. To remember everything I photographed every note worthy item. Then I will junk everything. My computer history started with a NASCOM 1 single board computer using the Z80 microprocessor. According to Internet wisdom, this board was designed in 1977 and then sold from 1978 onwards. The size was about a single A4 paper. I bought my system used from a friend of a friend in early 1981.
