🇷🇺 Партнер 01.01 (Partner): Part 10 (Running Test Program TPP2) [TCE #0485]
28Quick update ... got some software loaded! Big thanks to Peter G. who forwarded me some genuine WAV files.
First stop ... the test program TPP2 that came on the original, bundled cassette.
@MrWaalkman also did some testing and noticed a difference between the RKP-to-WAV converter I was using (compiled on MacOS from alemorf's Github repository (below), and the one included with the EMU80 emulator.
So I will be trying that one next on some RKP formatted files.
The files that Peter sent me can be found on our Discord in the "партнер-0101-partner-🇷🇺" channel.

From the Part 1 video:
It's a machine built in 1990 and looks to be quite well made with a magnetic reed-switch keyboard (more about that in a future video). It's actually based on the Radio 86RK (Радио 86РК) homebrew/DIY computer.
Incredibly easy to get into, to pull apart, clean and to service - keyboard, motherboard and PSU all unplug from each other.
Nice.
The machine has three 27C64A EPROMs and four cloned Intel chips:
КР580ВМ80А (KR580VM80A) = Intel 8080 clone
КР580ВВ55А (KR580VV55A) = Intel 8255 clone (PPI)
КР508ВТ57 (KR508VT57) = Intel 8257 clone (DMA controller)
КР580ВГ75 (KR580VG75) = Intel 8275 clone (CRTC)
On the left side it has a cassette port (МАГ), a video output (ТВ) and I assume a +5VDC output (+5В).
On the right side it looks to have a home-made joystick port - a DIN socket (surprise!) that is connected to the cursor keys on the keyboard.
