Old computers are my hobby. I have lot's of different Ataris, Amigas, PC's & others in my collection. But let's get to the point - I think this "unknown" processor comes from a Polish Atari clone known under the name of "JUNIOR". They looked like Atari's, but had a bit bigger black cases and were definitely less stable due to bad quality of components. And they were cheaper. You might want to check on that, because i'm not sure about all this, and I do not have a Junior computer in my collection. Maybe someday I'm gonna have one, because I know of a school that has some of these stashed deep in their basements but they won't give them away. Anyways, maybe You'll have more luck.

OK so here I am back again on this page after all this time, but now I can say with 90% this processor is from Elwro 800 Junior computer.
Here is some technical data of this machine (off polish wikipedia):
