I think it’s a mask diagram not a die shot, in any case these features are common for that era especially for the metal layers / ic traces look at die shots of a Z80 and it’s clones.
- ahartmetz 5y agoAh, yes. What do I know... but this Russian CPU still looks much more "weird" than a Z80! The Z80 has 90 and 45 degree angles, this thing also has like 10 degree angles, and wavy structures, and big curves, and triangles.
- Treblemaker 5y agoI'm curious to see where you see the odd angles. When I zoom in sufficiently all the shapes seem to resolve to segments of 90 and 45 degree angles.
- ahartmetz 5y agoWell OK, there is only one triangle - in the upper left corner. The other things I mostly see in the center and right of center. Especially in the blue lines - power and clock or so?
