About terminals from various vendors...
A major trend in the video-terminal business during the past decade has
been for companies to
merge, change names, and/or acquire lines of business from each other,
so tracking the affiliation of some terminals can be difficult.
(The other significant trend has been toward using desktop computers that
emulate a dedicated terminal.)
As the Twentieth Century recedes into recollection, many computer users
who have recently joined the club are unaware of how many different
(and, alas, mostly incompatible) character-cell video terminals were
in wide use during a large part of the 1970's and 1980's. This
proposed 1989 update of the list of terminals in RFC 1091 may give a hint
of the variety that once thronged the marketplace, before the industry
Another snag that newcomers to computing hit: the expectation that
documentation must exist on the
for every piece of equipment that was ever made. For equipment sold after
1996, this expectation may be appropriate. However, for older gear,
you are likely to be disappointed.
Even into the 1980's, the user manuals for many video terminals
were actually written on electromechanical typewriters (e.g., IBM Selectric),
and no machine-readable original ever existed. If
some older documents are Web-accessible, it is because
some public-spirited person
has done the techno-historical grunt work of converting old documentation
to a form readable by a Web browser.
For glimpses of how computer hobbyists of the early 1980's used character-cell
video terminals with the home computers of the day, you can visit a library and
