A while ago I posted a bit of info about a Russian desktop PDP-11-on-chip clone. Today I stumbled upon a couple of operating systems for a home computer BK-0010, and wanted to share a few screenshots from those. It's possible this is going to be quite unlike to what you've seen!

A few interesting things, before we begin:
* This computer series has a funny naming; for example, one of the models is called БК-0010.01Ш
* The keyboard layout is not QWERTY, and the default code page is not ASCII or PC-compatible CP866 but (almost) KOI-8
* The CPU is compatible with PDP-11, so the computer was used with RT-11 quite a bit. There is a modern UNIX V6 port for it, but, sadly, it was not a thing when the computer was still popular (only its older sibling DVK got a true UNIX back in the days)
* Designed in 1985, it was manufactured until 1993, and was still popular in the late 90s (but not as popular as ZX Spectrum)
* It has an unauthorized port of Monkey Island 2 with music and an alternative ending from 1995!

@nina_kali_nina It is a pretty system, probably because it appears to only support graphics. You mention that it only has 32KB of RAM, I reckon the other 32KB of memory is used for video display?

(Looks like a 640x525 display resolution based on some of your posted pictures, which would take up around 42KB, so I'm now starting to think that video is off in its own pocket of memory, kind of like how the C128's 80-column chip works.

Looks like the BK-0010 is pretty much everything I wanted for my Kestrel-2DX system, but I never got around to completing. See thread by Nina Kalinina for more on the BK-0010 and what the Kestrel-2DX could have been.

@vertigo Thanks for asking! The screen is 512x256 = 16K. The basic model had only 32KB (512 bytes for stack, 15.5 kB for data, and 16KB for screen). A later model had 128KB thanks to banking.
