I was reading some other threads on here from a few years ago about producing alignment diskettes. I'm in need of alignment diskettes for 5 1/4" 360k and 1.2m drives, and would gladly pay for them. I have some 1.2m drives that seem pretty well aligned based on their ability to read disks from 40 years ago, but the 360k drives don't seem to have fared as well. At first I thought the media was bad, but the good 1.2m drives have had no problem reading all the disks I've tried so far (including 360k-formatted disks). I need to align some drives from TRS-80 Model I, III, and IV, as well as PC drives. I probably don't need to worry about FM format, so DS/DD and DS/HD should cover what I'm doing. I have the Tandy alignment software for the TRS-80s, and a good scope. Would also like to find the MS-DOS version of "Tandy Drive Controller" (as seen in this Tandy service video on drive alignment:
).
On the off-chance that anyone is interested in selling hardware that can produce alignment disks, I might be interested in buying it, and making alignment disks available at cost (or less...) for those in need.
Also, if anyone has a collection of information on test points for various drives, that would be great. Some appear in drive data sheets, but others I've had trouble finding. In particular, I didn't see test point info in the datasheet for at least one of the TEAC drives I have.
