Can you describe the problem in detail? I recall that
you're using a
16FDC with 8" drives that are not Persci brand. Are you aware that
the 16FDC 8" bus is wired differently than what is required for Shugart
compatible drives? The Persci drives did not have a TG43 signal so the
write current may be too high on the inner tracks of a non-Persci drive
mated to a 16FDC
-- causing errors.
Fortunately, it is possible to modify a 16FDC to be compatible with a
couple of cuts and jumpers. I have some photos and text that describe
the mod.
I have always found it interesting how quickly people will go chopping
up circuit boards. Before you do this, consider chopping up a ribbon
cable instead. Ribbon cables are cheap and easy to replace if you
later change to a different make of drive or if you simply screw up
making the modification. I run SA-851's on my 16FDC with a simply
modified ribbon cable.
