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.
