This was a storage tube, vector addressable. But it also had a complete ASCII terminal emulator built in, with diode matrix character generator ROMs. Also the best keyboard I ever used, with magnetically-operated reed switches. The Tek terminal used a specially modified KL11 terminal interface, which did serial communication to the CPU at something like 100k characters/sec. This made the hard-copy TTY-based editor really easy to use, because it could repaint the whole screen in a fraction of a second. carl -- carl lowenstein marine physical lab u.c. san diego clowenst at ucsd.edu
