I think there is not a space issue, since the "modification" is in the end the same length as the original setup with the neck connector installed.

Good point Paul, i should have tested it while it was still not casted, but i dont receive my suit that i ordered untill tomorow..



Anyway, its Hot silicon glue, so it is removable with some heat...  Cheesy



We will see what happens guys, if it aint working, i can still try to fix it in another way
perhaps by casting those wristwatch pins instead of wires Smiley

Later more, it was starting to get cold in my shed, so i went inside..

Well...   2 times bad luck today  Angry

when i was creating a creative plug to enter in the original connector, i broke the connector  Evil
the plastic was so fragile after all those years, it cracked when i tried to enter the nails that fitted last week..

anyway, i cutted the connector off and connected the wires straight to the new wires that came out of the neck.
(first i folowed them and labeled them in the correct way)

Then i took a piece of cable and connected it to my stepdown converter since it was set on 115 volts..

I waited and waited and nothing happened.
I could only hear that highpitch noise that you listen from a tv also.

So i removed the neckpart and soldered them again to see if i maybe missed a connection, or if one came loose while casting it.




This time i tested it again without casting it, but the same result, no neckglow, and only the high pitch noise..




So it was two times bad luck, 1 broken neckconnector and one fix that did not work  Angry.



DAMN!!!!!

Well at least i gave it eveything i could, but i am affraid the tube is gone..

I dont know if you got another black - white monitor, then you can transplant the plexi with the art.

Or if its true what andre says (that it delivers component video) you can hack a tv which has a component input in there.
I guess it does not matter if its a color tv, since the board outputs black and white.
just find something with the same tubesize i guess..

Sorry i did'nt succeed, even the real macgyver fails sometimes  Wink

High pitched noise? Is that from the neck/tube? If it is, I've had that when the vacuum is blown  Embarrassed

I think so too....be careful !

At least the artwork can be transplanted to another B/W monitor.

I would not go with a color tube though. It can be made to work, but there are two issues:

1) the dot-pitch of a B/W tube is higher. This _is_ noticable and doesn't look right
2) convergence is never 100% on a color tube. When you feed it B/W signal that is so "simple" as that of these games (just a few grayscales probably) you will notice the slightest convergence errors because there will be red/blue edges on the graphics, esp. in the corners.

Of course everyone should decide for themselves, but I'm sure that Ully managed to pick up a B/W monitor here or there during all his arcade adventures...

Oh, and remember that we still have a working chassis....if Ully can find a nice working B/W TV in Germany, he's all set Smiley

Well thank you so much for trying the best you could!
Great that we can remove the artwork on the monitor because I think I've located 2 nests of TEC monitors but none are 100% confirmed.
I should know more wednesday evening.
Stay tuned.

thx so much for trying, etienne, i was hoping it could be fixed, but obviously it was beyond repair. once again: THANKS!!!

Ully, do you want me to remove the tube, the plexi, and then ditch the broken tube ?

IF the plexi can be removed easily, please do so, but only when you are certain that it won't get damaged. it would be a shame if we lost it. but i believe in you and your macgyver techniques. do me a favour though first, please take a picture of the plexi placement on the screen so that i know where to put it exactly later. thx a lot!!!

And that is what i did ofcourse  Wink




It looks like they have mounted it a bit shifted to the right.





here is more space between the edge and the plexi, but i think if you center it it will be perfect.





They have produced this in mass so it can very well be that they did not put too much effort in it to have it exactly in the center..

Anyway, its getting hot in here so lets open the window  Grin





Then i discovered something on the glass of the tube..





I know you love those details so i saved that too for you by sticking it to a piece of plastic..





Details for connecting the yoke again later, the other connections i have send you in your email.
did you received it Ully ?





Discharged it,  removed the tube and Yoke.





Leaves a bare frame with chassis here..





Lets clean it a bit, soap, water and a soft cloth to prevent damage..





And to remove the residue, it took a ride in my bathtub  Tongue





Its very flexible plexi, so i could scan it..  and ofcourse i dontlet this opportunity pass  Wink





stitch ready..





slide it into bubble wrap...





Packed and ready for pickup  Wink



Its safe in the attic, so the plexi is saved..

Let's take a moment of silence for this poor old B/W CRT. Through an insane twist of fait, it had been in storage for a couple of decades. To everyone's surprise, it was a live and well even after all this time. Glorious times would be lying before it again, for some caring people found it and were ready to rescue it from it's dark fait.

Then....the sadest thing possible happened. How weird that a poor manufacturing quality of something simple like a frame would end it's life after waiting so long.... Cry Cry Cry

RIP old friend !

However, the monitor became a part of a very good thing, being the definitive rescue of the wonderful CRT artwork !!
Anyway....there are still b/w TV's left who may be able to donate their CRT for this ! Smiley

Etienne: you were pretty lucky that the artwork didn't start flaking !!

Amazingly strong and good artwork after 34 years !

It on the back by the way, there i used even more caution while cleaning, but its supertight on there and no chips at all
(i checked that ofcourse before i began  Wink )

that is one incredible amazing effort, etienne - and so nicely documented!!! thx a lot for your hard work, unfortunately it didn't pay off. but at least you could save the plexi and i'm sure one day it'll serve its original purpose again.

btw, i could get a working 23'' b/w TV for 50 euros shipped. is that a good price? should i go for it? chris might be able to get a replacement monitor, but it can't hurt to stock up on b/w tvs as well, can it?

Pretty expensive but on the other hand, B/W TV's start getting rare too....

If it's working and the tube is OK looking...worth it I'd say (incl. shipping).

Luckily B/W CRT's are much easier to replace (no convergence worries).
