I've got the 2100 now. no paper tape reader :( oh well....
it's a HP 2100A main chassis, i -THINK- it has it's full compliment of
boards,
I also have 2 HP 2640B terminals that went with it (according to the guy
I got it from)
he may also have 2 more of the terminals.
one of the keyboards has some plastic damage but they -look- like they
should be functional.
unfortunately he doesn't have any of the cabling except the one connected
to the terminal's keyboard.
