I finally made the big step and got a controller that supports DD. Nice
to have 600K per disc (I have 801 Drives). I did have my share of
problems getting my memory up to 4 MHZ and the disc controller working
with my Z80......but I did it.
The only problem remaining is that I need help in creating a
double dens. disc that I can boot from. Currently I boot up a single
dens disc and then put in a double dens...then a Control C and I'm
there. The problem is the CCBIOS which supports the double dens
configurations is too big for tracks 0 and 1 when tracks 0 and 1 are
single dens., so I must put a single dens. version(of BIOS) on the boot
tracks.
I did try to make tracks 0 and 1 double dens. and then patch
in CCBIOS(DD) but could not boot disc.......the info from CCS is scarce
and not very helpful......
Is there anyone out there that can help me?
