Playchoice 10 wont play games & help with cart. adaptor...

[linx310]

I just bought a single monitor PlayChoice 10. It was garage kept and is very clean. The owner said it worked fine for years and then just a few weeks ago it stoped working correctly.

 

The machine boots up into the menu just fine.

 

But when you select the game you want to play the screen freezes or goes black for about 10 seconds and then it goes back to the main menu again.

 

Once it returns you to the main menu the game you just tried is missing from the list.

 

You can then select another game but it will do the same thing. Eventually the list will be empty.

 

The only way to repopulate the list is to restart the machine.

 

 

I have tried putting one game (i have 5 total) one at a time in each slot (so 10 tries for each game) and it happens on all of them.

 

 

Does any one have any idea what could be wrong?

 

 

 

 

 

 

 

 

I am also working on an adaptor to take NES carts. with a new bios but i am stuck.

 

 

Ok here is where i am on developing an adaptor so the Play Choice can take a regular NES cartridge.

 

The play choice main board's game slots have 96 pins aranged in 3 banks of 32 pins each

 

Bank A: A1 - A32

Bank B: B1 - B32

Bank C: C1 - C32

 

Now the standard NES cartridge has 72 pins. So the leaves 24 pins unacounted for.

 

I used a FAMICON schematic that used the exact same terminology as the play choice schematic and I think I have come up with a decent conversion map.

 

The "pins" I have marked in red and blue correspond to the pin number on the NES cartridge. Ex: Pin 38 (on the NES cart.) would connect to Pin A21 on the mainboard socket. The pins in Blue I am not to sure about since they are labeled "similar but diffrent"

 

Pins that I don't know where to put from the NES cartridge

 

pin 37 CLK 21.47727Mhz (NTSC)

pins 16-20 Expansion Pins

pins 52-55 Expansion Pins

pins 34-35 SECURITY

pins 70-71 SECURITY

 

 

Pins Left on MAIN BOARD I HAVE NO IDEA WHAT THEY DO/ARE

 

pins A7-A10

pins A11-A12

pin A29 (could be another sound connection for pin 51)

pin B1

pin B2

pin B3

pins B4-B11

pins C2-C9

pin C11

pin C10

pins C14-C21

 

So what I need to do is find out where pins 37, 16-20, 52-55, 34,35,70, & 71 of the NES cart. go.

 

 

 

Any one have any idea?

Sounds like the interface card is screwy. It's been like 5 years sence I last worked on a PC10 though.

My guess is it's related to protection. Have you tried one of the bios's that bypass the protection.

 

 

I had 50 blank pcb's of my adapter made so I will probably sell some of them eventually. Maybe even soon. I've done a lot of other stuff since then. I don't remember what most of those lines do.

TC, just to let you know...maybe you do, I don't know. Somebody has written a bios and made an adapter that allows NES games to play on a PC10. I've seen a page about it on the internet...somewhere. I imagine if you find it you'll probably figure out how to make the adapter as well.

As far as I know I'm the only one that's actually built an adapter. Getting the NES cart to run is actually pretty easy. The real problem is keeping the NES cart from interfering with the the PC10 carts and other NES carts. That's fairly easy with a pc10 cart since you know what the hardware is exactly, with an adapter you don't know what's going to be in there.

I'm curious since I'd love to get more use out of my PC-10 countertop, but without the coin-op menu it kinda beccomes a funky TV playing home games.

 

I'm pretty sure there was a guy who made a PC-10 game board where you could pop out the eproms to change games, like he was making NES games onto emproms and then plugging them into the board. Still no coin-op menu though.

Tabletop PC10 is the only way to go dude!! Cool to see someone else who has one. You do know the tabletop is the rarest PC10 there is right? When I sold mine I made a fortune on it. The Wells-Gardner tube in those things are easy as hell to swap with old TV tubes if it ever blows also. Prob my fav arcade I've owned for sure.

Yeah I've learned a bit about it over the years, its like a bookend to my coin-op vectrex. Both run off timers rather than lives or credits, which in someways is lame but hey they're all my quarters. I got really lucky on that deal, some guy posted to a newsgroup that he wanted to trade a broken PC-10 countertop for a working vectrex. I took him up on it and it turned out that it was just loose connections on the inside, one of my friends took it apart and rebuilt it and it worked perfectly. It came with 20 or so mini-marquees and 10 games, since then I've picked a few up on ebay but nothing for a couple of years. Chicks dig the PC-10, as soon as they find out its got Dr.Mario.

 

I swear the eprom thing was real, the guy had a tengen tetris one and IIRC a hack of some game to have bin laden in it.

 

EDIT-

 

this might be what i was thinking of
