On the VAXstation II that I ran in college for one of the departments
we would do TEK plots all the time. The programs that did them would
send an escape sequence that would kick the normally VT100-ish
terminal emulator on screen into Tektronics 401x emulation and then
send the sequence of tektronics escape sequences to do the plot. We'd
then take a screen shot of the plot if we needed to print it quickly
(but at low quality) on the laser printer, or we'd fire up the
Tektronics Plotter and redirect the output there if we were doing
photo-ready for a conference or paper. This was all on VMS 5.4 running
DISSPLA... We did have 16MB of memory, though....
