Quick Forth Question

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.
