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
