Interesting... what Televideo terminal is that? Did it have MS-DOS support?
I'm... Not sure actually! All I have is the mainboard, a piece I've had since my late childhood, before I kept any records or marked parts as to what they came from. (still not great at that, to be honest)
Anyhow, a more useful answer is- These are the markings: TELEVIDEO SYSTEMS INC., 965 P/N 132970-00 REV. G-H-G (not sure on the H there, badly faded paper label)
Further markings: Barcode label- M965X10901157CG and Silkscreen: X715A448-2 (no other pertinent marking as far as I can tell)
List of socketed chips: U16 - SILICON LOGIC 271582-00 (c) 1105A9006 (PLCC-84); U21 - MOSEL MS6264L-10PC 9031AN1 (DIP-28);
U24/25 - ST MK48H64LN-70 99012 (DIP-28); U14 - S SCN2672TC5N40 KHT7316 9018KA (DIP-40); U10 - CMDu G65SC816P-5 8836 (DIP-40);
U9 - ST M27512-2F1 89021 (DIP-28); U8 - ST M27256-2F1 89019EN (DIP-28); U7 - HYUNDAI HY6264LP-10 9024D KOREA (DIP-28);
U6/5 - UM6551A 9021S (DIP-28); U4/3 - MOTOROLA MC1489AP RQFV9020 (DIP-14); U2/1 - S MC1488N FHK6778/FHN3269 9035VJ (DIP-14).
Non-socketed chips are mostly 74-logic, aside from IC 401 - TDA1170N 89023 (DIP-14-ISH?), U101 - TI TL494CN 9018BR PORTUGAL (DIP-16), and U201 - CQY 80N 006 A TFK4 0883 (DIP-6, makers-mark: VDE, likely an opto-coupler)
Has two DB25 ports on the back, labelled MAIN and AUX, and an RJ11 jack for the keyboard.
CRT was built-in and there were no external adjustments for it, aside from a slider for something. (brightness or contrast, maybe?)
Sadly, unless I sent it in for decapping and possible repair, the U9 ROM is unrecoverable.
I recall, as a child, playing with the board and trying to get it to function while hooked up to its CRT sans the case.
I'd removed (some/all of?) the socketed chips and I reinstalled that ROM upside-down because the label is printed at the opposite end to the other one.
When I turned it on the clear window lit up like a light-bulb! I turned it off, reversed it, and tried again, but it was toast.
Don't recall if anything displayed on the screen at all. I've since lost all but the board to improper storage/breakage.
Anyhow, please let me know if you do get a positive identification on it! Might have a (small) chance at resurrecting it then.

do you have any idea which HP terminal the eprom came from or what the part number was on the label?
it looks like it might be a different version than what I have for the 900/94

No luck searching using markings/labels, but the rear ports match the 700-series! (700/60 and 700/96 both have the same port layout, 700/32 doesn't)
Now I really wish I'd kept the CRT, as I don't recall if it was white or amber phosphor. (don't recall if the CRT was saveable/unbroken when I got it, either)

Found a cache of video-cards in a box recently, dumped all the BIOS chips for you folks.
Mostly 16-bit ISA, pair of PCI and a pair of AGP cards. Included in the ISA bunch are three Realtek VGA cards! Never knew Realtek did video cards.
Also got three different ISA Oak Tech cards, an ISA AST Research card, the two Diamond PCI cards, and the two unmarked/off-brand Nvidia(?) AGP cards.
There's only seven unique cards with all the duplicates, so the only reason you get nine dumps is because some cards have HI/LO BIOS.
Anyhow, enjoy! These cards were all pretty clean so it was easy to get clean dumps, aside from one that threw up a bad checksum error despite verifying correct multiple times. Please let me know if anything looks funky!
Once I get a good power-supply put together for the 386 board I recently rescued from the garage (and its expired Varta battery) I can test all the ISA cards! (well, almost all, one Oak Tech card is missing an entire chip and has some minor trace damage)
That's all for now! (extra card/chip data in the text-file as usual)
And yes, I updated the GitHub too!

Small 386 update, dumped the HI/LO BIOS chips from my Unknown (Infonet?) CPU-3216SX 386 board that I've been working on, almost have it fixed.
I think I got a clean read on these, as the chips are in great shape, but I can never tell with these HI/LO ones, they just look like semi-intelligible gibberish in the hex-editor.
Have a look and let me know, please!
