Very cool. Wish I had kept all this stuff. It would be cool if you
could scan this.

I did some terminal firmware for a customer in the early (pre-PC) 80s. I had
to refresh my memory, so I dug into my musty-smelling files and turned up
two documents that I worked from. The first is titled "PRESENTATION LEVEL
PROTOCOL VIDEOTEX STANDARD", dated May, 1981 from Ma Bell. Unfortunately,
that standard doesn't discuss multiple character sets, so attached to it was
a section from another standard titled "Teletex Zeichenvorrat und Kodierung
(basierend auf CCITT Empfehlung S. 61)" that covers character formation
(among other things) from multibyte codes. Anybody else dabbled in NAPLPS? (ANSI X3.110)
I remember reading about NAPLPS in BYTE at the time it came out. I
never heard of anyone that actually implemented it.. Does that count as dabbling? I think I still have the
engineering prototype
PCB for the terminal wandering around... It feeds an OEM CRT monitor kit
and takes a (now missing) serial keyboard.
Even cooler. If you do find it, you should take pictures. Can you
divulge the brand / customer?
