wow, i must have missed it. i'll look again. my battery has been updated but doesn't save high scores after shut down of course.
Anyone replace a working Q*Bert power supply with a new ArcadeShop one?

it's called "Q*bert Battery Conversion Kit". it's 2 STMicro M48Z02 16 kb SRAM (http://www.mouser.com/ProductDetail...=sGAEpiMZZMvaNBfR/smQG3q6CQ8OY03ucOkqmh/jIa4=), which you put in place of the two RAMs on the right on the board. and a jumper which you replace diode D2 with. the 470 uf cap comes in the "Q*bert CPU & Sound Board Cap Kit", separate from the SRAM. or at least this was all true as of about 6 weeks ago when i ordered them.
you can also use simtek STK25C48 NVRAM instead of the STM SRAM, but those chips are more rare i think (though i think i recall coming across some thread in these forums where someone said they had a bunch of them).
EDIT: you can also use the Dallas DS1220AD or similar - see http://www.jrok.com/sohs/qb-upg.html for instance. they're more expensive, but at least you can buy them (http://www.mouser.com/ProductDetail...GAEpiMZZMutXGli8Ay4kC27Vf1CC6Grh%2bEB6a1P2tk=).

wondering if this sound mod necessary if you already have the arcadeshop replacement power supply installed? I have the arcadeshop power supply and so far so good.
thanks,

I have 4 spare Dallas 1220 AD chips from my Pole Position project. Looks like I know what I'll be doing for my Q*Bert as it's put back together.

Cool. I guess I would have someone build it for me since I dont have the technical know-how. Since people seem to have issues with the AS PS switcher conversion, it seems there is a little bit demand for these.

As mentioned earlier in this thread I ordered the AS PS. I installed it tonight and also added in a sound board (mine was missing from the game when I bought it). I hooked it all up with very little trouble, but when I powered it up, I got no video or sound. I did get neck glow, but no video nor LED illumination on the AS PS. I checked the AC and it said I was getting like 175, which seemed odd. I got no reading at all on the 5 and 12. Not sure what is up. I tripled checked everything.
I am doing this on a cocktail, so the boards/harness were a bit tough to work with, but I am certain I plugged them into the AS PS board properly. I checked both the "1" pin location and also based on the gap in the pins/connectors.
My game was working previously, minus sound, so I will likely put the original back in to verify everything is cool, but does anyone have any idea what I may have done wrong or what is up?
Thanks a lot!

I got my stuff from AS tonight. I think I am only going to install only the battery mod for now. I am gonna roll with the original PS for now since it is all working. Crazy?
I don't think so. I mean I plan to run the original stuff, but to be fair, I can't ever see my Q*Bert being on for hours at a time. Even in a party type situation the game would probably get turned off if nobody is playing it. I don't have power easily located at each game anyway so it's not practical to have all of them on at once.
This thread makes me want a Q*Bert

Yeah, Q*bert is a fun game for sure. The big seller is that I think my wife would love it. Everything in CA is too expensive though, and shipping blows too. Unless someone had a working project (cosmetics, etc) in the $400 range I wont ever get one.

I played My Q*Bert this morning for about 15 minutes. Great games on the multi. I am actually hooked on FHMC Q*Bert right now. I also really enjoy Cubes. My sound seems to be working again, but I think I am gonna replace the chip at U17 on my soundboard. I replaced U16, might as well do the other one. It's been a while, anyone know what chip to order? (I'm not at home to check) Also, any TLYZ fans out there? That game rocks too. Love it.
Hehe I've been on the 6 year plan with my Q*Bert. I bought it at a Super Auctions (converted to Dragons Breed) and have been piecing it together since then. Here's where I'm at with it. Still need to get the back door mounted, but a lot has been done. I even got the new cpo and lower overlay put on last night. Since I hate sanding and painting, getting that part done the last few months has made a huge difference. Now I feel confident in making that final push to get it done.

I need that multi-kit. Who sells these?

I see Mike Doyle made these. Looks like a lot of hacking going on!

The fuses seem fine on the brick. I put the original PS back in there last night and the game worked (although the graphics were a little tweaked and I had no sound- but that was going on before as well). So it seems like either the AS PS is bad or I did something wrong. I triple checked everything I did, so not sure what is up.

Yeah, it's a great game. Mine isn't going anywhere. My side-art should be here today. W00t.

It's also a game that isn't easily playable in Mame so it's a good one to have in the line up.
