Tektronix 4010/4107 Terminal Emulator Package

[Harvey S. Cohen]

AT&T Tango does 4010/4014 emulation, as well as vt100/52 and 
4410/5410.  A neat feature is the ability to toggle between
TEK and character emulations while preserving the other screen in
memory.  E.g., log in and do calculations as a AT&T4410, draw a picture as
a TEK4014, go back to AT&T4410 and your calculations are still on the
screen, go back to TEK4014 and your picture is still on the screen.
