This MME 80A-CPU based computer was an implementation of the circuits described in the book “Praktische Mikrocomputertechnik” by Manfred Kramer.

Some info on the book here (in German) - maybe some of you will recognise it:

I still love the minimalistic design!

A more practical question: How would you come up with the BIOS and BDOS adaptations and PL/M compilers in the GDR in order to run CP/M on a custom machine? Where the resources available and well understood? (English documentation probably provided a serious language barrier.)
