I have a complete TRS-80 Model I that has a dead
Western Digital FD1771-01
chip in its expansion interface. Does anyone know if a National 1771-B01
is a suitable replacement? What would be a fair/reasonable price for a new
1771 these days?
B. G. Micro,
www.bgmicro.com, has FD1771s for $4.95.
Thanks for the info. I should be able to get my local vendor to match that
price since B.G. Micro is a fairly well known vendor.
What is it that makes you believe that the 1771 s the problem?
Well, I accidentally plugged the chip in backward when troubleshooting the
floppy interface right after I got it. It turned out that the floppy
ribbon was bad, just due to age I guess. I don't think the chip let out
its magic smoke, but it certainly does not work now ;)
