Yes, but these weren't bent (at least by me). They plug into normal
IC sockets in a carrier module that plugs into the side of the HHC.
They aren't the ones that go inside and must have their pins wrapped
around a plastic carrier. There was no evidence of repeated bending
on any of the pins.

Okay, I figured out the immediate problem. Three
of the pins on
one of the EPROMs have broken off. One was hanging by a thread
and fell off when I inspected it. I see no evidence that the pins
remain in the sockets so I guess they must have fallen off when I
removed the EPROMs to read them in my EPROM programmer. I suppose
this suggests that they may have fallen off *before* I read them
and that is why your SnapFORTH ROMs don't work. I don't think
that's the case though because I'm sure I would have noticed
that. Do EPROM (or chip pins in general) get more brittle as they
get older? I've never had this type of problem before. These are
gold colored (and plated I assume) pins if that makes a difference.
They definitely get brittle if repeatedly bent.
