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) • Sergey's excellent reproduction of the Radio 86RK: • https://github.com/skiselev/radio-86rk • -------------------------------- • Check out my Patreon for regular blog-type updates between videos - there is a free membership tier and two paid tiers (US$2 and US$5).
