M1 CPU without revision, with manual routing of tracks from a microcomputer Elektronika 60.
Condition in the photo - you can see that it was being repaired and neatly cut palladium containing blocking caps. But, as it is, there are probably no more such.
Best known condition. The very first revision is practically not found, and if it does, it is in the worst condition.
If you need an authentic goldceramic K581IK1 for restore, I will attach it for $20.
