This is a DEC VT-132 Video Terminal. Designed on the same basis as the VT100, the VT132 has additional Block Mode function; that is, data can be entered by the user in blocks, typically into cells like a spreadsheet, and then the whole data can be sent at once. Standard terminals like the VT100 only operate by sending every key stroke at the time it is pressed.
The VT132 can display both 80 and 132 columns, designed so you can review data printed on a 14″ wide reports without wrap around. With the support of a line drawing character set, the VT132 was a very useful terminal. Additional user settings could be stored in non-volatile RAM to make its operation easier still.
