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?
