Which FDC? I've had trouble with the original 1793 controller chips
(the early programmed ones with the painted over window on top) going
bad on a couple of 16FDCs I have. Replacing with a newer hard programmed
plastic package chip and then recalibrating the data sep circuit solved
a bunch of problems. The 4FDCs tended to just be "twitchy". I think
there was a known problem with the controller chip used on them.
