I finally got this finished! It was a difficult one as I was only getting the odd 20mins at a time to work on it. I had a faulty replacement 6821 with no scclock output to the alpha... I initially swapped this but swapped it back when there was no improvement, but found it later when I came back to check it with the scope... I ending chucking this mofo 6821 across the room. The original alpha had a dead FET but no hole in it like usual. Which is 95% the tell tale sign...on the 12v ones anyway... My spare alpha had an issue where it wasn't internally Resetting... even though the reset from the 6821 was good. On the first boot with it, it always stopped the whole machine dead from coming out of reset... nightmare! I sussed out what this was by unplugging each plug on the board to see what area the fault was. With the alpha display unplugged it booted perfectly every time. The second boot with a new 6821 and the reset fault display worked flawlessly- any other resets or door closes after that and it was just garbage on the alpha display. 3 separate issues all in the same area! I recapped and changed the FET on the original alpha and presto it finally works... resets nicely and displays perfectly every time.

Hello, i want to change from a noob to a fun player. 👋

hi guys,quick intro,long time player /nerd of fruites...Help Chris217 with his facebook page,pretty well known amongst the community Nice to meet all of you x

Hi Mark and welcome, what machines do you have ?

just trying to find fellow fruit machine enthusiasts i have repaired and played for nearly 30 years and have 3 at home i would have more but the wife might cry

do you know what version software is on the Machine?

I have 91's, 93's & 802's (as well as others) but no 92's

Which immediatley makes me think of the Boogie Pimps video Somebody To Love (call me what you like ) 😈

Love the connector pin outs. Such a good idea as you can only see the numbers on the back of the connectors once removed from the board.

yes they change the memory mapping on the mpu4 is one of there functions

I had to suckle on the milk of human kindness lol 🥵😆

Ah, they are different to the standard mpu4 game card modules. And I guess they will also have a chk chip, so I cannot just buy any video program module and burn adders and ladders eproms. ☹️

😇 not always the villain

I have a couple of the cards with ribbon cables

Mark... PM me your address I owe you a bunch of flowers 😆 🤣 20260322_101804.mp4

I managed to find some images online and the program module looks alot different to a usual mpu4 fruit machine game module, plastic cased. althought it is from a different machine.

Dil 8 if I remember? No I dont think ive tried that!

Turned on the dil switch for front openers? 🤷🏻‍♂️
