CP/M for the iCOM 3812 dual disk drive with the Altair 8800 (88-2SIO) The recommended disk images to start with are: CPM14-3812-48K.dsk for CP/M 1.4 CPM22-3812-48K.dsk for CP/M 2.2 Use PC2FLOP in the "Disk Image Transfer" folder to write a disk image to an 8" single sided disk. PC2FLOP for the 3812 can format the disk, if needed. Once the disk is written, you may want to put PC2FLOP.COM on the disk to make it easier to create other disks. Use PCGET to load PC2FLOP.COM onto the disk. CP/M 1.4 Notes: Run MOVCPM to size for a different amount of RAM. Must use original syntax, e.g., "MOVCPM 48 *" to size for 48K or "MOVCPM * *" to let CP/M size the RAM. Then run SYSGEN to write the image already in RAM to the boot disk. CP/M 2.2 Notes: Run MOVCPM to size for a different amount of RAM. The "*" syntax is not required (e.g., "MOVCPM 48" to size for 48K or "MOVCPM" to let CP/M size the RAM. Then run SYSGEN to write the image already in RAM to the boot disk. CP/M drives C: and D: map to physical drives 0 and 1 (e.g., A: and B:) but treat the drive as a single density drive. This allows copying files between a double density and single density disk.
