Alice Averlong🏳️⚧️on a scale of 1 to WE COPYRIGHTED THE FUCKING PLASTIC CASE OF OUR DUMB TERMINAL, how many layers of IP law are you on?
it's a well known fact that injection-molding piracy was rampant back in the Reagan era
dang it. I did a decent job cleaning up this part of the case but I accidentally put it down the wrong way and damaged a clip. I'm gonna have to shim & glue it to have it attach properly
This is going to take forever to clean. I basically can only clean one channel at once with a cotten bud, and even that is tricky
significantly cleaner! qtips, paper towels + spudger, and toothbrushing it got basically all of it.
they didn't remove the little peely plastic protective film! This thing is from 1986! that's 38 years of PEELING LEFT UNDONE!
So I resoldered the couple of questionable caps and put it partially back together, but it's still got the RAM issues. I was kinda hoping the caps would alleviate that problem.
I still can't get into the testing mode since I don't have a keyboard for this specific unit, so I can't figure out which memory chip it is that's failed (and there's like 5 on the PCB)
Darn. I soldered in my new caps on my other terminal, and it's still got no vertical deflection.
I'm gonna have to dig into the service manual more and maybe do some oscilloscoping.

dang it. I have to copies of the WY30 manual. One is badly scanned, and the other... is missing the one page I need.
The good news is that the vertical deflection is built around the TDA1170N, an ST chip for generating vertical deflection for monochrome CRTs. And I've got a datasheet for that, so I can figure out what's going wrong from there
aardvark@foone I’m sure a GPT could fill it in LOL
jhannafin@foone I've not had much luck with fixing vertical collapse with just capacitors Usually it's a transistor somewhere along the way that needs to be replaced.
Farbs@foone Have you tried shaking* it?
*Up and down, roughly 50-60 times a second.
Cecelia@foone It’s dead, Foone! /Star Trek reference
Rue Mohr@foone probably a broken solder joint on the driver chip. Did you make an in-circuit capacitor tester?
Felice@foone It might be worth noting that you don't seem to have full horizontal deflection either.
Though I guess that could just be due to accidentally turning an H.SIZ (or whatever) dial. Does it have H/V size dials?
@Felice yeah. I've not tried adjusting those yet, as I'd need to leave it on to do that, and I don't want to burn a line into this CRT
Trit’@foone Very Windows 9x defragmenter-like! ^^
X ΘΔ@foone wonder if you could find out by just pullin one out at a time, or swapping them
PunnO)))@foone If you have replacement RAMs, you can piggyback them.
Take the known-good chip, bend the legs in a bit, and slide it on top of the suspect part so the good one's pins make contact with the suspect one. If your problem goes away (or, sometimes, changes in a meaningful way), that's probably the bad one.
It's a low-grade technique, but you can't argue with results.
joel b@foone looks like something you brought home from the Tatooinian market...
Kevin Boyd (he/him) 🇨🇦@foone Tatooine. Dantooine. Dustooine.
Yes, this is clearly the exhaust port of an imperial base on Dustooine.

(neet arc)@foone was it always this brown-ish or is it a UV protective sticker (mostly joking)
@instereo256 great question. Going by their old magazine ads, I think they were always kinda brownish? the front is a whitish-beige, which has definitely yellowed, but I think this darker brown-grey part has always been that way
Stormgren@foone @instereo256 I have two wy-60 sitting in the basement in good shape, i can get pics when I get back from Chicago on Friday and send over if it would help
@Stormgren @instereo256 nah, but thanks!
fun fact: I'm currently repairing & restoring two Wyse terminals: This one is a WY-30+, but the other is a WY-60!
@foone @instereo256 despite supporting serial terminals for years, I don't think I've ever seen a -30
Brian Swetland@foone @instereo256 I owned a pair of second-hand Wyse 50s back in college in the 90s, and they were sort of a medium gray. They just had simply pivot stands, not the neat telescoping sort of thing pictured in this advert.
Charlie Stross@foone @instereo256 Wyse terminals were grey. Source: I used to work using them in the early 90s.

Ditto. Gods, that was so long ago.

@foone what sort of monsters were these people?
@joshourisman well this belonged to Lucasfilm, so... yeah.
enantiomerAAAAAAAAAAAAAA
Miau 🥺
:labrys-xf-p: HighPriestessTerra :labrys-xf-b: 
@foone apparently you see that on a lot of jp stuff. They kept stuff in pristene shape usually either that or its sunfaded to all hell and back
Laukidh@foone someday I’ll sell off some old electronics and someone will have that same reaction to my stuff.
Holir_@foone that is impressive. I would be tempted to the air hose to it.
