Here we have another "serially produced" version of the Soviet-era home brew computer Радио-86РК (Radio-86RK) based on their Intel 8080A equivalent, the КР580ВМ80А (KR580VM80A). This fellow comes from Мукачево (Mukachevo) in the Ukrainian SSR (as far as I can tell). There was a 16KByte version (УМПК-Р16) and this 32KByte version (УМПК-Р32).

00:00 ... Intro
00:49 ... Important warning
01:20 ... Discussing the unique JCUKEN keys
04:15 ... Examining the case
06:24 ... Opening the case
09:00 ... Removing the keyboard
10:20 ... Examining the motherboard
15:04 ... Channel thanks & outro

It is a pretty simple machine, nicely made if we ignore the membrane keyboard with a dozen space bars. It has a four-pin socket for power in, a 5-pin DIN for cassette, RF-output for TV and a DN4612-style expansion port (СНП?).

As it's an 8080-based machine it requires ±5VDC and +12VDC.

My understanding of the special keys on the JCUKEN keyboard layout (thanks to ‪@Mercury13kiev‬ & ‪@sergijtolmeros‬ for their input!):
[ВК] = Возврат Каретки = carriage return
[ЗБ] = ЗЗабой = backspace
[СС] = Специальные символы = special characters
[ПС] = Перевод Строки = line feed
[СБР] = Сброс = reset
[УС] = Управляющие символы = control characters
[АР2] = Автоматический Режим 2 (automatic mode), or more recently Альтернативный Регистр 2 (alternate register)
[СТР] = Система Трансформации Реальности, or [CTRL]
ВКЛ = Бключить (turn ON)
