Ms Pacman Cocktail
StuDaBaker:
Ok, I'm getting back to this, almost a year later. :dunno
I've had some difficulty troubleshooting the suitcase power supply. Beyond checking the fuses, I'm not sure what else to do to it.
I haven't had any luck getting the board to do anything, and I even ordered another MS. Pac board with a multi-pac installed on it. Still nothing. Bought a used monitor off of a local guy here in town that I saw working on his test bench, hooked it up to the board I purchased and still couldn't get any signs of life, other than monitor glow and the pcb getting pretty hot.
So I've made a decision that's probably not going to be too popular with the purists. I've gutted the cab completely and purchased a 60 in 1 arcade classics jamma, board new jamma cocktail harness and just ordered a new 19" Imperial CGA CRT monitor. Since I didn't want to make any irreversible changes to the original cabinet, I've decided to shelf the original control panels and have new cocktail multicade control panels on order, also. That way, I can hopefully get this cabinet to a functional state and get it playing all the pac games I wanted out of the multipac, as well as some additional titles that I like.
The only thing that I have some reservations about is swapping the original cocktail monitor frame to the brand new monitor. I've read where ppl have swapped vertical and horizontal monitor frames without much trouble, so I'm assuming that this will be a similar operation, but just something about taking apart a brand new arcade monitor in a world where these are getting harder to come by that makes me a bit nervous.
So here's the new plan:
1. Get back to repairing the bottom right corner on the front of the cab. I'm going to try opt2not's suggestion of repairing the laminate with a piece of what he stripped off his Canuck's cab. (Thanks again).
2. Once I've received monitor and cp's then I'll bench test what I've got to make sure I've got working "guts".
3. Install everything into the cabinet, including monitor frame swap. (my goal is to have this completed by Thanksgiving)
4. Then, as time allows, I will work on the details, such as new monitor bezel, refurb or replace speaker grills, new cocktail glass, etc.
5. Also, as time allows, get back to troubleshooting original hardware on bench test: "Suitcase" power supply, original PCB (I returned the one with the multi-pac), original wiring harness (which seems to be perfectly intact), refurb original control panels. This way, if I have all working Ms. Pac parts, I can put it back in the original cab and move the 60 in 1 to another cabinet I either acquire or build. If I can't get it working, then I'll know it's more than I can do and sell off those parts to someone who can use them (with the exception of the original cp's).
I'm planning on using a pc power supply to power the 60 in 1. Does anyone have any suggestions on how they wired their cab so that the monitor and board turn on with the same switch? Thanks.

Sigh...there goes another classic.
Did you follow step one and check the voltages from your power supply? If you don't know how to, you could have asked.

Spyridon, I came here to the BYOAC forums years ago researching for a still not started MAME cabinet project and have now purchased 3 original arcade machines instead, largely due to what I've read in many of your restoration threads (and others). There's no denying your work is impressive.
I mean no disrespect, to you or anyone else who use these forums, but from your reply I can gather that either you did not fully read my last post, or do not believe what I wrote. I would love for this to be a dedicated Ms. Pac ct. (see #5 in my last post). I would not be opposed to building a new cab for the jamma parts I've purchased, but if I can't get this ms. pac to work, or someone to buy a non-working game, I might as well use it. Nothing irreversible would be done to it in the process either. But I'm not here to debate converting/restoring, so anyway.
--- Quote ---I've tested the fuses for continuity and they all check out. I don't know enough to know how to check the other components here, or even if the multimeter I have is able to correctly do so. Is it even worth trying to get this power distribution assembly functioning correctly (assuming it's not) or should I look into installing a switcher and a new shielded isolation transformer?
I'm guessing this is what I need to concentrate on at this time, making sure everything is getting power. Pardon my ignorance. Redirection, suggestions and comments are welcomed as usual. Thanks in advance for any guidance.

So, again. I am new to this hobby. I know more about arcade machines than anyone I know, but I'm not ashamed to admit that is squat compared to the enthusiasts on these forums. That's why I am here.
I do not know how to check voltages on this power supply. I do not know how to check voltages on a Ms. Pacman board. I unfortunately do not have time to take a class to learn all this on my own. So I am asking for help, please.
saleem:
whats the point in buying cabs you seem to know nothing to very little about.you dont or have not even learned to solve power supply issues and how to test them yet you went and bought more cabs.when the other cabs are not working what will happen to them ones then?
will you go and mame or shove a 60in1 into them also?
you are going and making the same mistake most of us make when we get our first cab.you will be cussing if you carry on with this hobby when you realise what to do and how to do it to get cabs running.
when it comes to power you need to know how to read schematics,grab a manual for the machine,look at the wiring diagram and the setupo for the transformer and see what wires carry whatr voltages,set the meter correctly to the setting you are checking/vac/dc whatever and probe the wire and see what the voltage is and what it should be,if the voltage is not right then correct it.
it could be something as minor as a diode or a capacitor that is not working right/shorted and needs replacing.it could be your line filter or any one number of things that is wrong.it might not even be power related and it could be a wire is broke inside the plastic that is around it.basicly it could be anything.
wish people would realise when they get into this hobby what they are getting themselves into.rather than panic and just give up.

Well, thanks for taking the time to reply. Very encouraging.
