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 system, both in HW and SW architecture. We had one of these machines and 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. alan

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.
