Reading MZ-80A/B discs on PC - Help please !

Post by luxmalc »

Amongst a bundle of 5.25" DOS discs for file copying are some which just would not read on my PC. Omniflop imaged one OK but didn't name the oddball format - just said it was 35 tracks x 2 sides x 16 sectors of 256 bytes = 280k. Only format on the Net answering this geometry is Sharp MZ-80A/B. 22Disk didn't list this exact format though it did support MZ-80 ... but this failed miserably. Allegedly the licensed version of 22Disk did support an MZ-80B but this is no longer available.
I'd much appreciate help please with .....

- is the MZ-80 floppy format significantly different to the 80A or B ?

-if it is indeed different, does anyone have the CPMDISKS.DEF entry for the A/B please ?

Thanks in advance

You are going to need to find an MZ-80A/B floppy disk to NTFS floppy disk.
If you are a programmer, go ahead and try to make one yourself (if you do, publish the software in a zip on the forum) but if you aren't I have some steps:
  1. Look around the forum for the MZ-80A/B floppy disk to NTFS floppy disk software
  2. Look around the original website for the MZ-80A/B floppy disk to NTFS floppy disk software
  3. Google around for the MZ-80A/B floppy disk to NTFS floppy disk software
  4. Emulate the wanted disk software (if it's a game or something like that)

Thanks - will give that a whirl !

Meanwhile does anyone out there have a licensed copy of 22disk v1.42 or later ( which allegedly supports the B) who'd be willing to post or pm the lines of the DEF file for the B please ?
