So the real VFD came in to the workshop as dead, and it was. These devices are quite pricey and I did warn the owner it might not be repairable. However trusty soldering iron in one hand and meter in the other I dived in casting caution to the wind. It has 3 electrolytic caps, 2 x SMD and one through hole. Both SMD caps were effectively open circuit but all three were changed to 105° types. Once these were done and the device powered up the screen was still blank so I needed to drive it with something. Looking up the spec sheet it showed that the SIN/TO pin, if grounded, would switch to test mode and by jove it did, displaying the whole character set. Sending it back for testing expecting a glowing report proved a bit premature. The device was still dead and the machine would only boot up without the VFD connected?? When it arrived again at the workshop I swear it was poking it's tongue out at me. Anyway not to be outdone it was time for a bit more researching. Next to no info on the web, no diagrams or fault repairs on Youtube. So first step was to find out why it was stopping the board from booting. This VFD connects to the 14 way DIL connector via the little PSU board. The only wire which goes directly from the VFD to the board is the BUSY link. I assume this is used to slow the main board logic when it needs to print lots of text to the screen. When this connection was removed everything burst into life! Checking with a meter showed it to be permanently HIGH. Here's a pic of the board so you can see what I was dealing with... Did the BUSY line go direct to one of the LSI chips because if it did that was goodnight Vienna! Trying to trace tracks on this was no easy task either but the BUSY line did appear on the O/P of IC2. This was a single OR gate and the output was stuck high. Checking the I/P showed a nice waveform but nothing on the O/P. I managed to find some replacements on Ebay at a reasonable price and slipped in a new one and bingo, nice waveform on the O/P and with the BUSY link re-connected everything burst into life. You have to take precautions when reworking these boards due to the proximity of other components and plastic parts. Best thing for this is Kapton tape to shield the bits you don't want melted.

HI looking for mpu6 clear down file if anyone has it many thanks in advance

https://www.fruitemu.co.uk/ib/files/file/924-max-a-million-manual/ Not had a look myself, just going by the title as i noticed it the other day looking for something else.

What are you looking for? And are you still looking?

Does anyone have this manual please?

Thankyou so much 👍

Will have a look Phil prob later in the week

Evening all , I have been building a reel crazy for the last couple of weeks but I am missing the yellow start button 🙄 I don’t suppose anyone as one spare happy to pay plus postage many thanks

Hi i am andy, nice to meet everyone! Looingforward to being able to play and chat about fruit machines old and new!

Hi Everyone thank you for letting me join the site Id like to introduce myself Im ibmxc05 and ive been emulating for a few years now and looking forward to getting back into fruit machine emulator I have a couple of arcade machines , light gun setup , vitrual pinball machine and a fruit machine stored elsewhere which i intend to join the family soon I did have a simpsons fruit machine but it got dropped during a house move so not useable in its current state Just before covid hit I lost my dog due to old age and then lost my mum to cancer so was lost for a while and ended up delving into collecting robots and at one point I had over 100 , still got a few lying around still working away Also into crypto so full nerd mode and a big kid all over Anyways cant wait to get back into fruit machine emulators If have any questions dont hesitate to ask

What a great find phil .is the base missing? Would really love to see a good long vid of this one in action

Thanks for the Reply Bob. I thought about it and do you reckon it could be a .hex if its like a copy of original software rather than a Rom dump? Yeah mine seems like it doesn't display .hex files- im still on the ole xgpro software for the TL866ii Chinese programmer so its obviously not as good as the Dataman... it gets me by though

Not one I have seen before!

Well this is another one I picked up yesterday, conversation from exchanges unlimited i believe,, had a count up on the rear lamp mask some bulbs holders are not used but it seems to add up the to the exchanges unlimited,, ?? Does anyone remember this machine ?

No idea why it would have been stored as a .hex but whatever you loaded it into maybe thought a .hex was a text file. I suppose it depends on what file formats the program will accept. With my Data I/O programmer it just assumes everything is binary no matter what the extension is.

Hi ive never come across this one before. Im programming a sound Rom for JPM GuabClub. The rom folder has a sound .bin file thats 128kb which is the incorrect size for a 4mb Eprom... which all impact sound cards are set up for. There's a 512kb .hex file that looked totally empty in my programmers software. I renamed this as a .bin and could now see all the data displaying and that file programs ok and the audio works. Any ideas why this would be a stored as a .Hex file and why the data doesn't show up when its viewed as a .hex? Thanks

Hi all, would anyone be able to reprogram a Mars me126 coin mech for me. I just need the £1 changing to the new one. Obviously i will pay for it but would rather give the money to someone on here. Many Thanks Jim

Hello from England, welcome to the forum. There's many good people on here with lots of knowledge. Good luck with your machine.

Hi all, I think I mentioned these devices a few weeks back so I thought I'd purchase a few and have a play. If you're not aware these devices can emulate ROMs and come in all the sizes and will do masked ROMs too although I haven't got there yet. Amazing so far and so many things I haven't tried yet. They are about a tenner each but the time and effort they save it's a no brainer. The devices can be flash programmed in seconds so no waiting 20-30 mins to erase ROMs and re-burning when you're testing patches to code. Then plugging them in to test and finding they don't work! (yep we've all been there) Once installed in the ROM socket they can be re-programmed in situ via USB. Here's a pic using an MPU3 card... Also big and smaller brothers. They do devices for larger chips but I don't need them as yet. Another advantage of these is you can save multiple images which can be selected by the jumpers so changing code can be done in seconds. Of course in the case of MPU3 & 4 you can't put them in the case as it's not deep enough but that's fine just for testing purposes. Another advantage is you can put the whole image on one device and patch the CS lines to the empty sockets (not tried this as yet) but it's all explained in the blurb. I needed to use these due to trying to defeat the CHR and CRC check as burning traditional ROMs was taking all day. It can now be done in seconds. I'd like to thank John Parker for his assistance with this and taking the time to explain it. Cheers John you are a squire and a gentleman sir. For the guys out there that like hacking ROMs for changing the gameplay, I think these devices will be a godsend. It does also mention in the blurb you can change bytes on a running system, not tried that either but it's all terrific stuff.

Hi Everyone, My name is Hatfal, and I'm a fruit machine enthusiast from Hungary. I have just recently purchased a cabinet that runs on a Pluto 6 board. Unfortunately, the machine is currently not working and won't boot up. I noticed a specific symptom on the hardware: the 5V LED on the board is continuously blinking / flashing, and the machine stays dead. I joined this amazing community to learn, find relevant resources, and hopefully get some advice from the experts here on how to troubleshoot this power/boot issue and bring the machine back to life. Looking forward to being part of the community! Best regards, Hatfal

if like me you have a 4 pound HIT THE TOP MPU4 machine but it has the capped 4 POUND nudge roms (version 2.0) i have taken the 3 pound version 1 where the game is a million times better and changed the jackpot (proparly) to 4 pounds so you can play the better game inside the 4 pound display glass. HIT OR MISS is offered everygame and not capped to being occasional. and all nudges come out if you win the HIT and not just the amount needed for the win and you can save them back in again. Fantastic version of it and it still meets percentage. This is a 256k one file i use for one ROM but you can split it. if you cant then message me and i will do it JAMES 8 - - HIT THE TOP - v1 -ALL CASH - 4 POUND JACKPOT - beta 1

This is undxsd mfme if im correct?

As above does anyone have one spare?

hello there
