Ah, yes and editors other than EDT. Some apps are real hard on
compatability.

Also under VMS run "help set term/device" as VMS supports a large load
of devices.

< If I were writing a spec, I would try to cover all the cases.

Actually the pathological case is something you don't document, your not
supposed to do that or expect an particular behavour or it would be
documented. Convoluted, yep.

< One of the admins here mentioned that we have a big secret binder of VT1
< stuff. I haven't seen it yet. Was the firmware source code ever availa
< That would be neat to look at.

Firmware may have been available but meaningless. The tech manual and
the then user manual (5/8" thick!) were more than enough to write apps
for it.

< If the two sets of circuitry ran in parallel, that explains how a rather
< CPU could provide characters and graphics at the same time. :)

has nothing to do with cpu speed. It was a artifact of the VT100 having
the ability to mix RS170 video and data along with needing a bit map
for the graphics stuff that a character teminal would not have.

< Unfortunately, I have two specific programs I want to see. One of them
< DECRITE from DECUS (a ReGIS text editor -- runs on VMS). The other is E
< (The Wargame of the Century), version 5.0 (?) which is on magica.update.

Eewww DECRITE, gag. Never checked out the games.

< Even DEC's terminal emulator for DECWindows (which I would *hope* would
< very good, and actually does seem to be very complete) barfs at DECRITE
< I think I need a VT125 for that.

decwin doe work for regis if set up right. some apps will squawk as if
they interrogate terminal type they get the wrong thing back if set worng.
Under DECwin you have to create a DECTERM session as a vt125.
