This last bit was really problematic becuse the Z800
cannot execute the
VGA bios code
in the ISA board's rom.
Can't you get a VGA card where the registers are documented well enough
to at least put the think into a simple text/graphics mode without using
the BIOS ROM code? In other words, ignore the ROM and hit the hardware
directly from the Z80? I know I'd have tried soemthing like that if I'd
_had_ to use a VGA card with a CP/M machine...
