Ok, let me understand this. Now I will have Alex's Z80

into? � KOOL!!!!!!!!!!!!! �I gotta have a Carte Blanche.
The z80 on Carte Blanche is not a very practical design as the "real"
SoftCards and
clones are plentiful on e-bay and only run at 2 MHz. So using my PCPI
clone is more
practical if your goal is to run CP/M on Apple. However this project
is a very nice
example of what is possible to do with the Carte Blanche including
soft co-processors,
interface to real CPUs, etc.
The application that will be practical and will be pre-loaded into CBs
is a (mostly done)
VGA compatible video. I already have a fully functional version but it
is using a pixel
clock derived from genuine Apple timing - 14.28 MHZ that looks great
on analog VGA
but sucks on LCD monitors due to resampling. The new one rescans at 25
MHz just
right for VGA mode.
Anyway the CB is ready for production and we need to know how many to
build. Let's
start here. Who wants it?
