I'm looking for a VT100 advanced video option board. Or, failing that, if anyone has a
.100 spacing, 50 pin dual row female connector so I can makes one...
The circuit is really simple, it's just a plug-in board that gives the VT100 some
extra RAM so it can display 24 lines of text in 132 column mode, and do some extra
character attributes. I cooked up plans to build my own based on the schematics in the
printset (and using some newer SRAMs), but when I actually pulled the logic board out of
the terminal I realized that the header connector it plugs into is a stupid spacing - .1
instead of the usual .156.
