Quick Forth Question

[David Betz]

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.
