I am looking out for a couple of keyboards for project
systems I am assembling. I need a VT102 keyboard (the
original DEC one), plus an HPIL keyboard for a
9000/300. I think the HP keyboard carries the
designation A1099B.
You don't need an HPIL (Hewlett Packard Interface Loop) keyboard,
fortunately. Such things are _very_ rare, the only one I know of was the
one Garry Friedman made and described in 'Control the World with HPIL' as
an add-on for the HP71 (I must do something like that some day, typing in
long programs on the 71 itself gets tiring...)
What you want is an HP-HIL (Hewlett Packard Human Interface Link)
Keyboard. These were used on many HP machines, and are relatively common,
at least over here.
AFAIK all DEC VT1xx terminals (VT100, VT101, VT102, etc) took the same
keyboard. That may help you find one of those.
