Ha! I recognize those. They're spare boards out of
HP's 264x terminals.
Speaking of these terminals, I have a 2649a that is just old enough to buy
a Penthouse, sans keyboard/documentation. The cards are really pretty, as
Hans said, and unfortunately full of gold (which means they're probably
usually melted rather than just junked).
I'd like to be able to use this with my HP 3000/37 system, but need a
little help locating a keyboard and setting it up. I'll try on the HP300-L
mailing list too, but any info/pointers, as always, would be much
appreciated.
