Well, I also have a fully functional 6502 assembly kernel, with a little
bit of I/O (system via timers & some fairly iffy keyboard support.)  It's
all written in assembler (Microsoft 5.1b - the best *$%* assembler
ever <G>).

I'm currently working on the screen code.  I'm probably going to use a
varient of Mode-X (320x200 256 colours), setup for 320x256.  Using a 256
colour mode makes pixel updates easy, and the palette should make flashing
colours straightforward.  Another advantage of Mode-X is that you can
hardware scroll.

I think you're right.  Is any of the old mail available/archived somewhere?
