Hello everyone,
I've got these Nixdorf boards since recently. Does anyone know to what kind of machine
this belongs? The word "Kernspeicher" clearly points to magnetic core memory.
And when I look to the amount of power transistors it seems to be 12 bit. I really wonder
from what kind of machine these were. The boards date from early seventies...
And I wonder if anyone could actually use them to repair such a machine.
Regards, Roland

No, Nixdorf was a significant player in the computer
business in Europe, especially.
Wikipedia says they were the 4th largest computer maker in
Europe at one time.

Nixdorf was eaten by Siemens 1990 to form Siemens Nixdorf

I worked for SNI in Munich in 1991-92 porting SVR4 (branded as SINIX) to
a new 386-based multiprocessor system they were developing. I heard
there was a MIPS-based system that used the same chassis under
development at what had been Nixdorf in Paderborn.

That would have been the 'Targon 35' It was almost identical to a Pyramid

we could use the software released for Pyramid on it without any issues.
AFAIK, there was even some sort of oartnership between the 2 companies.

Eventually Siemens bought Pyramid. After that the hardware side of
Siemens merged with Fujitsu.
The architecture of the system that we were working on was described as
the same as another system with Multibus being replaced with Multibus
II, but I don't recall what that other system was.

Heinz Nixdorf founded the Nixdorf firm which later changed name into
Nixdorf AG. This is one of the parts of the Wirtschaftswunder.
Heinz N died in 1986 while on the CeBit messe so he basically died on
the footplate.
