43224 22JUL88-2319 Hardware Hacking
From: DEANL To: KDARLING
I took your suggestion and changed the jumper of my FD-502 drive 1, so
that both drives spin when one or the other is accessed. The mod went well,
and it has, in fact, produced the results you said it would.
My problem now is that I have an LED that is on continually now, as long
as there is power to the unit. I thought maybe you might be able to give me an
idea where the problem might be located. I used all the pokes you suggested,
the drive works absolutely correctly, except for that LED. The mod was clean,
without any problems, and I didn’t think I had changed anything else, but
obviously I’m getting a crossover somewhere. I thought maybe with you’re famil
iarity with the FD-502, you might give me a place to start, other than sending
it to Tandy for a repair. I don’t have schematics, or anything.
I’d appreciate any help you could offer.
