I recently did some drive alignment work for a customer and ended up doing a trade for some alignment diskettes. One set is a J&M Systems, LTD. package with a Dysan 508-200 "Diagnostic" diskette, and a "DISK DRIVE ANALYZER DDA V3.3" program diskette.

I stuck the Dysan diskette in a drive that had just been aligned and "explored" it a little with the oscilloscope. It's not a usual Dysan alignment diskette and does not appear to have the radial alignment patterns on it. Since I don't have any TRS-80 gear, it's not a ton of use to me.

If anyone is interested, I'd like to trade for another alignment diskette in some other format I can use. Let me know what you've got!
