The 8050 will work fine with any PET except, I'm assuming, an un-upgraded v1 ROM 2001 (due to bugs in the IEEE routines in the original ROMs). BASIC 4 has a number of commands that make it easier to use diskette drives, but even a 3001/2001-16 or -32 will talk to an 8050 just fine (but you'll have to load a DOS Wedge or use a lot of PRINT# statements). From your description, it's not entirely clear what's up with your drive - do you have any disks to attempt any read tests? If you have a problem with the write side of your analog electronics, then a HEADER (N0:...) is not going to succeed. If you can't read a known-good disk, then no amount of write testing is going to reveal your problems (unless you have another known-good 8050 next to the first one to test how the first one writes). Considering the 8050 is either a 96tpi or 100tpi drive (depending on the exact brand of 5.25" mechanism installed, IIRC), it's a much higher density than a 4040 or 1541. Are you using suitable media? I can see how a format test would fail with a working drive and bad media. -ethan Message was sent through the cbm-hackers mailing list
