I doubt anyone is much interested in changing the resolution - all the
software stops working.

Matt,

I am sure that all software will work fine unless HiRes and DHiRes are to be modified. Nothing is worried to modify any routines. All software should run fine at 1 MHz.

How do you propose to shift out 8 bits in 14 cycles of the 14MHz clock,
so that video reads still interleave perfectly with the 1MHz processor
clock?  Do you propose a 16MHz dot clock for text mode, and how would
that be synchronized with the 14MHz master clock?
