This was necessary, since they are shipped without a new version of CP/M. There is a card to order it from Commodore for $20, but it ain't ready yet. In case your're interested, I basically patched the portion of CXDISK.ASM which sets up TYPE2 disks. Change the 40 to 80 and 79 to 159. Then fill in an appropriate empty slot in the drive definition tables. I used 4K allocation blocks, and 1K physical blocks (it's necessary to format the disks in Commodore BASIC before booting CP/M). If you need further help, send mail, but I'll be unavailable for about three weeks. Ray Carter
