Vintage CRT industrial monitors

I wanted to show everyone what is inside some old industrial grade, high end CRT display monitors. These were part of a barn clean-out I am currently helping with. These are only 2 examples of about a dozen different brands from all about the same age; early '80s.
Disclaimer: no tubes were broken. All were sent to a local municipal recycle facility. :recycle: Enjoy !


First I have a Honeywell Terminal Display Model# B01650

The two boards were stacked under the power supply plate, all under the tube assembly. Yoke was very small so i'm thinking it was a monochrome, text only display.

Tektronix Display Monitor Model# LR3675

Two boards are heavy. Gold IC is soldered to the board unfortunately. I almost missed the small aluminum covered ceramic and gold Intel chip. Its only the size of a quarter. Yoke is heavy with a very complex power supply setup. I'm thinking this was ether color or a high end monochrome graphics due to the Intel processor chip and the bank of ROM.

Very, Very Cool. I have yet to see the inside of one of those older type monitors. I did get some older boat radars and found several high boards in those but no cool chip like the one in the last photo. Thanks for sharing. Mike

Wow! Cool find and thanks for the great pictures!

Nice find and thanks for the pics...I've never seen boards like that in a monitor...

I took apart about a half dozen more vintage monitors this weekend. Most were your standard CRT brown boards. Two were interesting.

Human Designed Systems Inc (HDS); Infocon, Model 2000G

The first one had a nice telcom board in the base, but the second one I opened up had a nice white ceramic NEC gold eprom.

I finished up my barn clean-out (finally) and got a bunch more monitors. Two stood out

Lear Siegler Inc. (LSI)
Model ADM-5

Very retro and futuristic

Board is toast but very cool. No good chips but a very nice telcom board

This would probably be worth some good money if it was in way better shape, but as it sits, borderline full scrap or just a desk weight. Ill just shelf it for now. TBD

The other monitor I will post this weekend when I get a chance to pull it off the trailer... Its HUGE

After looking this big monitor over, it looks to be a piece of lab equipment. X-ray or something. Its not that old but its big and heavy as heck. boards are disappointing but I thought i'd show it off anyways. Enjoy
