I was frustrated by other failed efforts: I'd
saved a pile of
known-working 5 1/4s, but failed to remember to inventory whether
the PCs I'd saved (of various generations) had the right connector:
edge or not, and I had no idea where I'd stored the adapters,
so more frustration.
Just grab the right connector from your junk box and crimp it onto the
cable alongside the 'wrong' one... What, you don't have a junk box?
