gferluga Posted November 6, 2016 Share Posted November 6, 2016 I got a bunch of floppy disks for the Commodore CBM PET system. On several labels is printed 8050 or 8035. Any way to access to data or programs via MS-DOS? For CP/M I use 22dsk142. Not familiar with Commodore world. Is there any tool for CBM PET disks? Thank you in advance. ---Giancarlo Quote Link to comment Share on other sites More sharing options...
carlsson Posted November 6, 2016 Share Posted November 6, 2016 Unfortunately you will need a 8050 or 8250 drive (I've never heard of a 8035, is that a typo?). These record 77 tracks out of a 100 tpi density, using GCR encoding of the data. I don't think anyone has come up with a solution to have a 1.2 MB HD floppy drive reading such disks, even over multiple passes. Regular QD disks record 80 tracks out of a 96 tpi density, which is what some of your CP/M systems may use, with FM or MFM encoding. Quote Link to comment Share on other sites More sharing options...
