KR580IK80A : Weekend die-shot

KR580IK80A (later renamed to KR580VM80A) - one of the most widespread soviet processors. Contrary to popular belief, it appeared to be not an Intel 8080A (or 8080) clone, but a code-compatible redesign (while several parts are quite similar, routing is different as well as pad placement).

Thinnest lines are 6µm.
