TEMPEST monitor advise !

[arcadefever]

hi,
i've been collecting arcades for a while i and think tempest was the missing one. i got it last week and i'm very happy.but i've a question.

-when i turn on the game it take 3 minutes to see the first graphics
-then it is only blue for another 5 minutes
-and finally all the colors appier.

the game can stay on for few hours with no problem but evry time i turn it on it's the same thing.

i know xy color monitor are almost impossible to found, so

do you guys know in case the monitor die where can i send the board to get fix?

know you know the status of my monitor what should i do ? leave it like that ?

thanks for your help .....

[arcadefever]

first i will like to thanks monitorguru for the help

one more thing for you i found this for xy monitor:


cost $160 and that will replace the deflection board it come with a pdf file with nice picture, i read it and it is really neet.
basically with that thing you need to remove the old board and replace it with that.just keep the high voltage.
what do you think ?

[ChadTower]

I don't think it will solve the problem completely, as you still have capacitors on the other boards that clearly need replacement.

MG, is there a way to tell from the outside of the case whether a TV has a 100 degree or 90 degree tube?

[arcadefever]

what other board ? you mean pcb ? or high voltage ?
because this replace all capacitors in the deflection board.

[ChadTower]

Yes, IIRC, there are more than one board in an XY monitor.  What model is yours?

A PCB is any board, that stands for Printed Circuit Board.

[arcadefever]

well this new pcb is like recaping the deflection board and most of the time the low votage on that board fail this thing will prevent it ...

 

[ChadTower]

Right, and it will fix some of the issue.  Not all of the caps are on that board, though, and therefore the caps not on that board will not be replaced if all you do is replace that board.

[arcadefever]

chadtower thanks for the update on that, that true will fix some stuff but not all of them.

i saw on "mike'arcade.com" he's selling new nintendo sanyo monitor. i just wish one day they will do that for xy monitor

[ChadTower]

It's getting there.  Nearly all parts can be had new now, and replacement tubes can be found, so it's almost there.  No one sells them all assembled, though.

No new compatible yokes, that's the real problem, if I understand correctly.  Apparently these can be hacked, but I don't know how.  Personally, I'll believe a brand new vector monitor when I see it (and probably buy it, too!). 

Chad, I see you noted the thread on Vectormame re: Sega vector platform development tools on Vectorlist.  Is this something you can work with? 

[ChadTower]

Probably not, my low level coding skills are very rusty right now, I have a ways to go to get back to being able to code at that level efficiently.  I've spent too much time in PERL/shell scripting land the last few years. 

I'm definitely following the work being done closely, though, and within the next year or two would like to be able to really contribute.  For someone who has C/assembly experience but hasn't really touched it in quite some time, is there a place that you'd recommend starting?  Maybe if you shot me some notes you have, I could start learning the board architecture now.

[Matthew Fisher]

I'm afraid you're asking the wrong guy about programming.  The last programming I did was about 25 years ago in basic on our TI 99/4A when I managed to move a little sprite around the screen a bit...     We got the Assembly language cart, and I hit the proverbial brick wall.  I imagine any number of people on Vectorlist might be able to help you, though.  For instance, I know that Jeff Hendrix was working on a color Space Wars for the Space Duel platform:

You might have missed most of the discussion on Vectorlist a few months back regarding this Sega platform issue.  I'm wasn't really able to follow it, but seems like the goal was to enable someone to program a new game for the Sega G80 platform that would work as a rom swap, or something like that.  If you can't find the thread in the archives and you're interested, I can send you copies of all the emails. 

[ChadTower]

Oh, duh, for some reason I thought you were the guy working on that project.  My bad.  Sounds like you are talking about TI99 LOGO.  I loved that, had tons of fun with it in 3rd grade.

I've been loosely following their project.  You have it mostly right on the surface.  What he is working on is a set of libraries to make it easier to develop a new game using that platform.  Instead of having to make one from scratch, you can have a set of prewritten, debugged, and known good routines you can call for certain time consuming tasks.  It's a modern concept retrofitted to an ancient platform.

[ChadTower]

Hrm... so, in general, the best way is to open the case and look for that marking on the tube?  Is there a list of some models that have it someplace?  Is that wishing for way too much?   

I wonder if a TV repair shop would be of help in finding a 100 degree tube.  I bet they see a lot of tubes fly past.
