Date: 1975. Digital's first upper/lower case video terminal. Its previous video terminals, the VT05 and VT50 (both of which we had in our PDP-11 machine room 1975-76), were upper-case only.

In 1978, DEC announced the VT78, which was a word processer made by putting a PDP-8 computer chip and some memory inside a VT52 and adding an external RX02 dual 8-inch floppy disk drive. This was the predecessor to the DECmate.
