Give a guy a finger, and he'll take the whole hand ...
... now that the demo5 is working in CP/M-80 and in colour ...
I've done some more tests
Demo5 is not running in CP/M-86 and MS-DOS ... and neither is DR DRAW in CP/M-86 and colour, but it is working in mono. Looks like the graphics emulation doesn't play nicely with the 8088 boards.
You need to run graphics.cmd and then draw.cmd from 8DRMO-M.td0 (mono) resp. 86DRDRAW.tdo (colour) from this archive. The mono version displays the splash screen and menu, the colour version just stalls.
On the third disk in above archive there is 80TGRAF.td0, another graphics library, this time again for CP/M-80, running CGDEMO shows some remaining alignment issues for the 7220
