Ah, but the store owner now had one more thing in the deal, an education, don't let anybody test your stuff at a fixed price. Its the kind of mistake easy for a basically honest person to make. OTOH Apple II drives are pretty hard to break, --- I still have a broken one, can I fix it myself? the only thing I know is when I put a diskette in and try to read it it goes rattttatt and gets an error... :^( ---- how did you test them? ----- I connected them to my apple II and put in a known good diskette, swapping the diskette to the other drive to verify it was still known good... :^) ----- Could it have just been incompatibility? Thats the second risk, customer tests your stuff pronounces it bad, but later on it turns out they (generic they, not you) didn't know beans and the stuff is just fine (which of course you find out after customer B buys it for parts and retests later).
