I think it will depend on whether the GAL security fuses have been blown. If they have then you're stuffed.

Hello friends, I have a question, is there any software that will help me edit data on the JPM program card? And another question is it possible to clone GAL on the program card?Thank you

Not sure if that's the Gottlieb pinball System80?

Found this on an old p.c maybe it's this? system 80 test.zip

how is your technical knowledge? and can you post a picture of the mpu3 motherboard. clear pictures of the printed circuit board.(pcb) so we can possibly have a look. it could be anything.

Replacing the electrolytic capacitors could be the solution. Even though they look good, they dry out and lose value

Hello and welcome 👍

good evening wanted to find somewhere to have fun with retro emulators of games etc looks like an epic site thanks for the memories fruitymunchkin

Pluto6 are programmed to match the manufacturer. A pluto6 for Astra will not work with a betcom CF card. They need to go to HEBER for programming which is not cheap. i know people who have swapped and transplanted chips from one board to another with no success. I’ve not known anyone to get round this but would like to know if possible.

Just joined up from Lincoln UK, hello 👋.

Hi Have now 5 maygay digital sound boards that have like a ( explode background sound ) when in machine. I know the issue is on the digital sound board. Working Nice on a working sound board. So any idea what component i may change on the board to get the sound clear again ? Is it the ampflier ? I have tried to rinse and clean the potentiometer. But no change on sound ( just change on volume so think they are not the problem )

No one seems to know about this machine, it's the same in France on Flipjuke .... I start to get scared... While I'm waiting for informations, I started listing the parts list. C1 10 µF 16 v DI 1N4148 D2 Zener 5,1 V R1 R6 330 Ohms R2 R3 R4 1 KOhms R5 100 Ohms TR1 ZTX 450 IC1 4069 UB IC2 COP 499 IC3 ILD 74 Battery 3,6V 100 ma

I cross my fingers, I might get a CPU this summer .....

Think the ram is surface mount, I have 6 of these boards, there are 2 types for JPM and blueprint which uses flash card

In my watchlist, anyone got a scalpel? 😀

If you're measuring voltage from the transformer then do it when it's disconnected from the MPU.

Eachway Shuffle is a JPM machine so won't be MPU3. Can you post up a picture?

Excellent al I don't blame you as frog it is a better game and looks better too .

Cheers nick i certainly did turn it back into a Frog It(and thanks to phill for sourcing me a couple of missing bits).

Could be anything! where are you?

I have an Adders and Ladders MPU3 it worked until last week until the machine went into a silly phase. Now nothing boots up. I have checked all the fuses and power out of the transformer supply. On 12V fuse I have 6V on the 36V fuse 13V and the 50V 56V. Does anyone have a service manual or can help with a repair.

Hi everyone, I have two MPU3 machines Adders and Ladders and Each Way shuffle. Adders and Ladders stopped working last week, nothing seems to be booting up.

The bord needs the ram, it wil not start when it is removed or somtimes wen it is defect. try an other ram, for your convenience, solder an ic socket on your motherboard, that also prevents track damage. and it is then easier to change the ram.

Bury St Edmunds ronnie so yeah it's a few miles away !😕
