Is there anybody knowing something about this series of process control computers?
The first model the 303 was build in 1965 using germanium transistor technologie. It is a series (6 models from 301 to 306) of 24 bit computers, single address and limited to 16.384 words of core memory. The different models were up- and downwards compatible, because the OS emulated missing instructions. The last in the series was build in 1969 or 1970 in TTL technologie and had an architectural extension for more main memory.
I dont know if they were used (sold) outside germany.
PS: I'm working on a emulator for the model 303.
