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?

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.)

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.

Unfortunately (or, fortunately if you are my wife) it's not "my" gear

anything small is sitting around. I'm not sure AnY DEC hardware will
ship for less than a small fortune.
Truck rentals...if that 11/780 is still there, I will give it a good home.
I'd give it a good home too...if I had the space, electrical service, and electrical knowledge to appropriately test the power supply. Along with the EE skills to rig up a MASSBUS emulator. (NO WAY am I going to get a MASSBUS drive to not fall through the floor here...and I'm not moving something that heavy down stairs to the basement.)

Yow.
Go check. I'll show up with a truck. (assuming you're in the USA)
Anyhow I did cart off a micro pdp 11/87 (?!?) that looked like it had
never been powered on (racked with about 20 others). Got a gate pass
for it but never brought it home hoping id soon be able to find a pdp
/ Vax implementation on FPGA soon and forgo the storage and power
(fire hazard?!?).
Fire hazard??
And I assume you mean 11/83. But that's a very small, relatively
low-power-consumption machine. Go grab it!
If it's low-power like a VS4000/60 grab me one too! You said you found
several! ;)
It's not quite THAT low power, but it's close. Probably less than
3x...i.e., nothing to worry about. Mine pulls something like 275W.
That's not bad at all. My V210s pulled more than 3x 60W or so.

Oh ok. I'll back you on that point. (though they were nice enough to
give some very fine hardware a few years ago...)
How much junk mail do they send after giving the hardware? ;)
Huh? I didn't get any. But then I don't think they ever had my
address.
Ah. I get lots of junk mail and email from 'em after trying their
stupid Linux certification practise tests. They were not vender agnostic.
Gross. I hate junk mail. No, I went to their headquarters with a
truck and picked up some big iron. One of their guys has my email
address, but they never got my postal address. It's different now anyway.
Ahh. Yup. A lot different now.
I can agree with that. One just can't get much better than "apt-get".
I'd agree. While apt-get isn't my favourite of the package managers
(does it support delta package updates yet?) I willl certainly prefer it
to yum. (You should poke at alpine's APK if you like apt-get)
Nah...I'll learn it if I need to, but right now I don't. I have lots
of other stuff that I need to digest.
Ahh. It has a plan to work on embedded stuff. You might need it one day.
Hmm. I tend to program on bare metal, or with a lightweight RTOS (see
FreeRTOS, I've used that in a number of designs), I generally don't
embed Linux.
Yeah, Linux isn't exactly suited for embedded stuff in my opinion...too big personally. I do prefer RTOSes for that but when I need an "embedded" linux i'd have to choose alpine.
But that sort of package management in that environment sounds like a
nice idea.
It helps with running tiny OSes for say: Xen. (VMWare doesn't like SVM on my system...Xen is fine with it and it gives me more control...unless I retrofit my own userland in to vmware.)
