I wanteds a 4x6 screen mode for a bespoke Z80 board with a 128x96 bitmap display… The likes of the ZXSpectrum sites have code for it, but they made use of lots of register rolls (enough of which to be slow).
Eh, I don't have much experience with Z80 coding (I was a C64 kid..), but it was fun.

…and here's the results.
The board has only 512 bytes of free RAM, that's only enough for testing the core routines with a few characters.. It'll get the entire ASCII character set when it goes into eprom.
