T34VM1 - soviet Z80: weekend die-shot

T34VM1 is Z80-compatible processor manufactured in Soviet Union / Russia by Angstrem in 1991 and probably later.
Die size 4513x4251 µm.

Marking on the die "U880/5" suggests that it was likely manufactured from mask set received from east Germany company VEB Mikroelektronik "Karl Marx" in Erfurt (MME).

We also made photo of ceramic package itself as it's quite rare chip:

"ОП" marking on the ceramic package means "experimental batch".
