Elektronika UKNC/MS 0511: the Soviet more than a ZX Spectrum, not-quite-Amiga [video]
- nxobject 3y agoAn educational personal computer, which debuted in 1987, that took the defacto Soviet standard platform, PDP-11 clones, strung two LSI PDP-11 clones off a single system bus, one controlling a 640x288 framebuffer, 192kb of RAM (with memory management, of course), and shoved it all in a keyboard: https://en.m.wikipedia.org/wiki/UKNC https://en.m.wikipedia.org/wiki/UKNC I am vaguely obsessed with it, since it pushes the PDP-11 architecture to its limits. It is surprisingly capable because most of the computer’s I/O was offloaded from the “main” LSI-11 (clone), to a second LSI-11 clone, that handled audio, graphics, etc. As a result, the MS 0511 had a vibrant game scene and demoscene. If you want a good showcase of tbe MS 0511’s graphical capabilities, here’s ~25 minutes of graphics porn, including 16-bit bitmapped graphics: https://m.youtube.com/watch?v=1dTXn5XU5Yo https://m.youtube.com/watch?v=1dTXn5XU5Yo And here is an emulation of 2-voice beeper sound: https://m.youtube.com/watch?v=RXoL5996f3s&pp=ygUEVUtOQw%3D%3D https://m.youtube.com/watch?v=RXoL5996f3s&pp=ygUEVUtOQw%3D%3... It had significant limitations, though - beyond only having a 16-bit data bus/17-bit address bus to play with, it never had a UI-driven OS; only clones of RT-11.
