Nice one Dave, me like!
Re: CP/M - 80 Column Board Graphics
I have hopefully faithfully recreated this, pixel by pixel, in MEMU, REMEMOTECH and REMEMOrizer, from printouts such as that.
In MEMU, the file monprom.c should be pretty self-explanatory.
It is interesting to note that you don't need to draw all the block character graphics, as their bit pattern is a function of the character code itself.
I use this fact in the REMEMOTECH and REMEMOrizer hardware to avoid needing 2.5KB of character generator memory.
