I've now added the hardware to the supervisor/monitor board to allow diect reading/writing to RAM. With some re-wiring one can also use this to program the PROM. This demo shows uploading data to the microcomputer and running code from ROM. We verify the code is working by examining the screen-buffer memory and checking that the processor is looping in the right region of the ROM.

Code and schematics: [ Ссылка ]. The state of the repo as of this video is tagged as "0.0.2".
