"NPR had a piece yesterday (I think) about some guy who has contracted
to have the original IBM PC style keyboards made again (naturally in the
PRC). Very heavy, spring activated, highest quality. Say what you will
about the folks at IBM, but from their years of making Selectrics they
knew what made for a good keyboard. As I remember, Pournelle used to
sing the praises of some aftermarket brand, but I would assume they
perished in the invasion of $8 throwaways. Alas."
The Northgate keyboards were resurrected as the CVT Avant Steller for a
while but that ship has sailed. I bought one for the office and it is
still being used daily. I think that this the keyboard that Pournelle
advocated.

The IBM AT buckling spring keyboards have been duplicated but I have yet
to buy one and test it out. I used to have the 3270 (122 key) version of
this at TXU since my pc had a full 3270 terminal built into it.
