I now have an A1020 external 5.25 drive and have purchased Dos-2-Dos so I can read/write MS-DOS floppies. Now I am looking for software that will allow me to read/write CP/M floppies. Is there a PD or commercial program that allows the Amiga to read/write various flavors of CP/M disks? My other computer is a DEC VT180, also known as a "Robin". The disks are single sided, double density, 9 sectors per track, with 169K of space for data. It has the following hex numbers in the DPB (Disk Parameter Block): SPT: 0024 = 36 records per track (9 sectors of 512 bytes each) BSH: 03 = block shift (for 8 records of 128 bytes per 1K block) BLM: 07 = block mask (for 8 records per block) EXM: 00 = extent mask (for 1024 byte blocks) DSM: 00AA = maximum block number = 170 (180K - 9K on 2 reserved tracks) DRM: 003F = directory maximum = 64 entries (which take up 2K) ALU: C000 = allocation in directory for directory itself (128+64,0) CKS: 0010 = size of checksum vector = 16 entries OFF: 0002 = offset due to reserved tracks XLT: 00,01,02,03 08,09,10,11 16,17,18,19 (physical sectors inteleaved 24,25,26,27 32,33,34,35 04,05,06,07 5 to 1 with 4 logical records 12,13,14,15 20,21,22,23 28,29,30,31 per physical sector) If I had the sources to the MSDOS program on Fish Dish #158 I could do it myself. But rather than reinvent the wheel, I'm asking of anyone else has a CP/M transfer program.
