Guys,
Saku Setala donated a VT420 a while back but the screen is almost unreadable, unless you turn off all ambient light.
Is there any way to fix this?
Increase the current to the electron gun.
How does one go about doing that? I'm more of a software guy, not an EE...:)

Well, if you're a software guy...go try and find a local retro TV/radio guy. They'll likely have the right skills and equipment to attempt to rejuvenate it. You'd be messing with voltage in the kilovolt range here...so I don't recommend doing it yourself.
Still, it's only going to be temporary. It might help it for a couple years, and it might last 20 minutes. Your best bet is picking up a replacement CRT or a replacement terminal.

Hello!
Are there any other settings you can tweak? Especially since I
believe that place sitter might be CRT based, so there might be ones
for the contrast and bright. (Remember those? They were found on
classic SDTV sets.)
There should be brightness and contrast controls on the right hand (as facing
the display) side of the terminal.
Tried all those, no help.

It might be increasing /voltage/ only with low current...but you'd need the skills to do ti safely and HV equipment.

The terminals themselves were just largish monitors and keyboard with an LSI11 system built in (an 11/03 or 11/2 - wasn't an 11/23, they were too new).
Even if you had one now, the magic was in the software that was downloaded from the TMS system, and the server side stuff that ran on the host 11. Without a TMS11 system to attach to, it would just be a bulky LSI11 system with no disk. Now, if you added a disk, and upgraded the processor, it would be the basis for an interesting desktop system - but it wouldn't provide the real VT71/72 experience.
Indeed. Then again, the download image would be the big thing -- the OS support for send/receive of files wouldn't be that big a deal. But unfortunately the odds of ever finding it would be very slim >indeed; I think TMS-11 had a total customer base of perhaps 100 sites, maybe a little more. And I assume those things all shut down quite a long time ago.
Crazily enough, I looked through my old files and found copies of the terminal download firmware from my old TSM11 system. On the extremely remote chance anyone ever finds a VT71, VT72, or VT173 (the VT100 shell version of this terminal series), let me know and I can provide the .LDA files that they loaded.
