Hi,
I'm looking for any kind of document and software for the Dietz Mincal 523
minicomputer, or anecdotes, user reports etc.
I don't expect too much feedback since this is an obviously very rare
German minicomputer from about 1970; it is a micro-programmed 19 bit
architecture with shared microcode/core memory.
But asking doesn't hurt ;-)

Found the picture here:
http://computermuseum.informatik.uni-stuttgart.de/dev/mincal523/
I have a core-memory board and 2 driver boards that have the same
edge connectors and very similar form-factor.
The core board is organised as 4 bit-planes of 100*96. Date codes of
7227 to 7423.
I have never had any idea what machine they belonged to, other than
it was German based on the writing on it. Not enough info to say it's
from a Mincal 523, but interesting to see the
similarity. I can put
up pictures if of interest.
