Operator's and Reference Manuals

Digital Equipment VT102
(Serial No. TA030736)
Circa April 1983

A fabulous piece of computer history -- Digital VT102 Video Terminal. This beautiful piece of equipment is clean considering the age. There is some yellowing, the bottom appears more so than the top. I fired it up and there appeared on the screen the number 4 with a blinking square cursor over it. Unfortunately, the test ended there as I have no keyboard for this. It made no crackling noises upon start and it appears to be clean inside (I took off the back to sneak a look).

PORTS:

unlabelled 25 pin (COMM. 2 maybe?)
COMM. 25 pin
VIDEO OUT (BNC)
KEYBOARD
20 ma. w/arrow pointing down (possible expansion)

This is a Terminal of unknown origen.
It is custom, in that everything seems to built in the keyboard unit, sans the monitor/printer.

This is a Heathkit Model IG-28 Color Bar and Dot Generator.
Circa 1969.

This is a Heathkit Model IO-1128 Vector Monitor.
Circa 1971.

Rockwell:

Rockwell 8R (Serial No. 218308) Circa mid 1970s early 1980s
This Vintage calculator has been fairly well persevered.

Operating examples found on the bottom of the 8R.
The calculator has 5 functions +, -, x, /, and %.
