Like Spiro said, later 1541 are write compatible to cbm-drives. But The 3040, 4040, 2031 HP have different heads than the 1541 has. I had a 4040 connected to my MMF and wrote disks for it with my 1541_at_zoomfloppy. But after some month I have problems to read the disks - I also tried the 2031HP - the same problems. Both drives are perfectly adjusted and cleaned by me - incl. speed adjustment. Fresh good 1541-written disks work great, but with the time I get problems. I also tried other 1541-drives to write disks - but still read problems... But The disks I wrote in the 4040 itself are running perfectly. I think the older cbm-drives have different write and or output power in the analog part. PS: Now I use only 8050 /sfd1001 disks in all my PET/cbms - and no problems anymore. ----- greets Christian -- Sent from: http://cbm-hackers.2304266.n4.nabble.com/Received on 2020-05-29 21:43:33
