tpdd is actually exactly the same as fb100 even down to the firmware. The only difference is the solder pads configure the drive to run at 9600 baud while tpdd has switches set to 19200 by default. It also means you can't do the TPDD1 bootstrap procedure with the TPDD1 util disk on a fb100 unless you change the solder blobs the same way as the switches. But you don't need to. You don't need ipl or floppy. ipl is just the first stage of installing floppy from the disk using the drive when you don't yet have floppy installed. Floppy is just a tpdd app like tsdos, but cruder. Since you have tsdos, you don't need floppy. In fact you can't have both at the same time even if you wanted.
That baud difference might matter in some cases but not for TS-DOS. tsdos knows about fb100, and Purple Computing and KnitKing rebadges, and autodetects the speed and switches to 9600. It sounds like you did everything right. The drive should have spun for about 2 minutes (about 100 seconds) while formatting, and tsdos shows nothing on screen during that time. One thing that we don't know yet is if the drive has a good belt. They all turned to goo several years ago, so every drive needs a new belt. Has yours been replaced? bkw On Tue, Feb 4, 2025, 8:49 AM George Hunt <[email protected]> wrote: > Thanks for letting me join the list.
