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.
