Super-cool Peter. No idea what device this would be from.

The Motorola chips are first-generation (1960s) ECL-gates, which were super-fast for their time (almost 10x faster than other technologies). Let me know if you have another one Wink

solved:

this PCB is a part of the Telefunken TR-440 Computer from the early 70's.
only 45 pcs of these computes were asembled, and most of them were
used in european universities. Smile

so from my point of view is this a really rare PCB.

Hi,
yes, it's a Telefunken TR440 card, and it's really rare and difficult to find. Note the PCB's organization with separate power and ground planes. This helps to reach the max. performance of the ECL circuitry. Great item for your collection.

Nice part - Sperry-Univac boards are probably
very common compared with this!
