In the 1990s a computer terminal standard "AlphaWindows" was proposed by the
Display Industry Association (DIA).
Sort of X-Windows for the poor.
A few terminals appeared which supported multiple text windows following the
this standard. Some limited global facts can be found in Wikipedia.
I learned that for example the TeleVideo 995 and 9089 or the HP 700/70
terminals supported AlphaWindows.
Obviously there were several implementation levels like:
(1) Basic AlphaWindow
(2) Mouse Operations
(3) Decorations
(4) AlphaWindow Credits Flow Control
Unfortunately I cannot find any information on the protocol resp. escape
sequences and the DIA is long gone.
Does anyone have a manual with escape sequences for one of the terminals
mentioned?
Or other material describing this protocol?
Note that other terminals of the similar types (e.g. HP 700/71) do not
support this feature.

Very poor... only text in the windows.

This is kind of interesting to me, because I helped get TVI 990/995 working in MAME.
We obviously never had the windowing protocol information either.
I wondered why a terminal needed a 68000 inside it.
I'm obviously interested in anything you come up with.
I guess a place to start is getting a copy of Multiview Mascot and watching the
serial protocol between it and a terminal.

Related.. I worked on a similar product in the mid-80's, except it could do Tek 4015
graphics in terminal windows. A friend just revived one of the board sets over the
weekend.

This was a board-level VME or Qbus product you talked to directly through a shared memory
queue of virtual terminal connections.

Interesting stuff. I just (a few weeks ago) saw a boxed copy of FacetTerm
for Unix at a store with a lot of old electronics and computer stuff. I see
now that FacetTerm worked with the AlphaWindows standard (although I think
it could do its own thing too). Looks like it's still available for Linux.
