[GreenKeys] More Teletypes with Mainframes

[Cory Heisterkamp]

We may never know... IBM loved their EBCDIC, but machines like the Burroughs and RemRand could be operated in straight binary, BCD, XS-3BCD(for Univac), etc. Since these console TT's weren't part of the regular I/O channels like later 8-bit machines, they could really be anything the designers dreamed up. Still, neat to see the TTY hardware no matter the code. -C
