Let's have a look at an 8080-clone based machine called the ПК-02 (PC-02) ... I believe ... a proposed upgrade of the ПК-01 Львов (PC-01 Lvov) ... ? This is currently guesswork - please don't have a meltdown and be a dick in the comments if I've gotten it wrong ...

The chips all appear to be date stamped before the breakup of the Soviet Union, hence the Soviet flag instead of independent Ukraine.

I don't have much information about this machine - it appears to be a prototype, numbered 6, in a repurposed case. The case & keyboard look to be similar to that used in the УДК (UDK) learning computer, or Учебный Дисплейный Класс (Instructional Display Classroom).

I've seen reference to there being a ПК-02 Фобос (PC-02 Phobos) as well as a ПК-02 Мукачево (PC-02 Mukachevo):

I'm thinking it might be the Mukachevo ... 🧐

There is also a ПК-02 Львов, however this is just an upgraded PC-01 it seems:

This machine runs on the КР580ВМ80А (KR580VM80A, an 8080 clone), same as the ПК-01 (PC-01). This means it uses clones of the 8080 support chips as well: I spied a КР580ВК28 (KR580VK28, an 8228 bus controller clone) and a pair of КР580ВВ55А (KR580VV55A, 8255 programmable parallel interfaces).

As it's an 8080-based system it requires +12VDC and ±5VDC (for the CPU, not RAM).

It uses the standard 5V КР565РУ5Г (KR565RU5G) 64kbit chips for memory, giving 64KB in total. There is also 16KB of ROM in eight 2KB ROMs, comprising seven КР573РФ5 (KR573RF5) and one КС573РФ2 (KS573RF2), labelled C0/C8, D0/D8, E0/E8 and F0/F8. Only the C0 ROM is socketed 😞
