Is this machine emulated? If not I’ve got the Roms for it, but no sound Roms!!

Dont know if this is any good to anyone or if it even works or how to use it as ive never tried it but attached is an Epoch development kit. It came with some PC cards to attach an epoch main board to the computer and rather than use the standard Epoch boot chip it used a bespoke one that allowed the downloading of program from the pc to some HM628512 static ram chips on the board instead of burning eproms epoch.zip

Hi there. I have a mayday machine of pick your pasos. I was playing one day and I got jackpot but had less than 20 in the pot and the alarm sounded. I turned off and on again like many times before to reset the payout but it got stuck with the LD1 Flashing, LD3, LD4, LD5 and LD2 are solid and L6 is off. The battery was removed before leakage and was working fine in a home environment. I have a video of boot up to show what happens if that helps anyone. Thanks

Hi there I have recently brought an impulse Pick your pasos fruit machine. it had slight damage from battery leakage but i have fixed that. I was playing yesterday and it was all fine and then the PSU started making a weird noise. i moved the machine up some stairs and plugged it all back in but the power supply seemed to stop working. does anybody have the pin out for the PSU / Power Supply so i can check the voltages. Also, on the main board (the one with the game and sound cards) and the LD1, LD2 and LD6 are not lighting up at all and the ALPHA lcd board doesn't get power at all. its not the cables but i think its the screen its self. Thanks in advanced

Hi there - I have Gridrunner - used to work just fine but been standing a while and now doesnt boot up at all, no lights, nothing. Once turned on I just have the three green lights - similar to so many other threads, and have the sound of the alarm kind of feintly hissing through the speaker. More recently now the top led(reset I think) is rapidly flashing and there is a clicking sound from the speaker....which eventually goes and solid green light comes on, but still nothing. The PSU has all bright green lights lit - bit noisy but think it always was.... I really want to prove the MPU faulty but its so clean and no sign of damage at all - but I dont have a clue how to test the board and roms. Can someone help me - Id love to get this back up and running Thanks Giles

I have an EPOCH MPU board that probably gone south, although I'm not 100% certain. No, i'm not just going to replace it as thats what everybody seems to do, then throws the old ones away which is stupid as these are going to become rarer and rarer. Simplified problem: The machine boots (partially) and most of the lights go in to demo mode, and reels attempt to move. But nothing more. Now for the techy bit. The problem in detail Power supply was buggered to start off with, as there was no -12v rail, which turned out to be a faulty cap whos ESR was way way way off the scale. I also replaced all of the caps on the board while I was there as some of them were a little bit suspect after 20 years. This stabilized all of the rails some what and got rid of some excess ripple that would never have helped. I also discovered a fault resistor, well at least what i thought was faulty anyway, R20 in the PSU which is the drop from the 240v mains power in to an opto-isolator via a dioide, was burnt and I was unable to ascertain the exact value. I believe that it is meant to be 100k, but I can't be sure as the colours were burnt off! This will adversely effect (and this is where I am guessing now) the sync pulse and/or the line power sense which could be the fault, but without a diagram or such, its difficult to say. The MPU board battery had burst, no surprise. It has destroyed a multitude of tracks, and taken a surface resistor and generally made quite the mess. Once the PSU was sorted, this board wouldn't boot properly and only three lights would show up. I repaired all of the broken tracks, replaced the surface mount resistor and cleaned up everything checked and double checked. The board now lights up correctly with top to bottom lights as follows. ON, OFF, ON, ON, ON, PULSE. The game then boots as described above. So I scour the web for a manual, diagram, schematic and none can be found, well the one I did find is in the maygay manual and is of such poor quality that I can't read it! The serial output lines have data on, and appear correct but again need more info on output pulses! It would appear as if the FPGA is not being programmed correctly on boot, as ROMS 2 and 3 are not being accessed. Chip enable should be pulled low and they are not, BUT this could be normal operation as we are only currently in demo mode. ROMS 0 and 1 are enabled and AFAIK are outputting correctly. This could just be a partial boot problem or it could be a dead FPGA, i am not sure. All of the pins on the FPGA test as per the Datasheet, but its a little ambiguous. The 16MHZ crystal is oscillating perfectly with a beautiful sine wave so no issues there The bottom line is, I know that I can repair this board, but I NEED a schematic or a better quality copy of the maygay manual. Or alternatively answers to some of the queries! Just to recap, R20 in PSU - What is the value? SYNC Pulse - What frequency/amplitude? Pink cable - Currently outputting a sine signal of aprox 4.7v, is this correct and again, frequency/amplitude? MPU - Are all roms accessed simultaneously? I will keep working on the board, as being able to actually REPAIR these rather than replace, would be eternally useful to all. So If any one has any info, it would be of great help. Thanks, Jody

I have a maygay Simpsons beer guide which has stopped working. I bought it about 5 years ago and it worked fine. Not used it in a while tho. Last year I turned it on and the alarm came on so I quickly turned it off. Yesterday I turned it on and it does nothing at all. No alarm, or sounds, just buzzes quite loud. sometimes when I turn it on it has question marks all over the display. I will post some pics in a min from my phone. On another post someone said the battery could have leaked. Could that be my problem? Thanks, Darren.

Hi, does anyone know where I can find a manual for an Impulse “Wipe Out “fruit machine, I am only after the manual for the dip switch settings on the epoch board, I have the Tech manual but not the one for this game play. Any Help will be much appreciated. Cheers. Peter.
