They should be normally open (NO) not closed. Maybe it's a translation thing? Mind you if you disconnected the wire it would have showed.

Welcome Sean, Great machines you've listed there, and I think we would all love to own at least one of those. 2p machines from that era, are very rare, and command a high price. There are a few members on here, that might point you in the right direction, of trying to find a good 80's machine. Well, from Chorley, you have Red Rose, plus Retro Fruits / Reel Fruits in Blackpool. I've only been to retro fruits, and I could spend a week in there, very easily. I was local (Liverpool), but currently living in Celina Ohio. I've got 2 machines over here. a Duff Beer Guide and a Big Brother. I'd like to have some 10 JPM machines such as Impulse, Roller Coaster, Monopoly, but the cost of shipping and now tariffs, is not an option currently. Welcome to the forums, we are a pretty relaxed crowd here. Regards Statto

Hi all, I’m new on this forum although I have had a passion for old 1980’s mpu3 machines for a long time I used to work for Nobles back in the late 1980’s and before then I spent a lot of my pocket money in the arcades of Primrose Valley as we lived close by, Filey and Scarborough. I would love to own a classic machine or 2 but they seem to be super rare now and very collectable and therefore cost a fair bit. My dream machine would be something of the big shot / circle skill / razzle dazzle era or perhaps a fruit preserve. I did love the old 2p machines as well - copperwin, blue streak etc I am looking at retiring from teaching soon and would love to treat myself with some of my retirement pot Until then it’s enjoying a few retro arcades - I live near Preston so I’ve been to Red Rose a few times and playing the emulator I would love to hear from any other local enthusiasts - I’m based in Chorley Sean

Hello. My studs are made of metal; what a shame. They'll stay that way; they're well insulated now. Yes, the push-button switch isn't stuck; that's the first thing I checked. I'll double-check this whole area before replacing IC4. As Bob said, it's not easy to do inside the cabinet. jjmXXX; it's a normally closed (NC) contact; if I disconnect a wire, it's the opposite. Thank you for following this adventure.

Does it still do it if you disconnect a wire from the back of the switch?

Those studs are made of plastic (or they should be) so they won't need insulating? The only metal ones are the two fixing the board to the chassis and two holding the ROM cart holder. Before replacing IC4 I would check if any other switches on the same line are working. I would also find out exactly which one it's on (9 or 10) then see what switch it is on the black connector and also the DIL switches. If you can find what they do it will be easy to check that IC4 is OK. You could put the scope on it and see if there's a waveform going in to IC22. With no switches operated there shouldn't be. Are you sure the switch isn't stuck on?

More to come, if you don't mind... My display was completely malfunctioning. But after cleaning and lubricating all the connectors, it's back to normal. (I used brake cleaner and a very small amount of silicone lubricant.) It's probably also because I properly insulated the PCB's mounting points. This prevents short circuits. As you can see in the photos, I used two layers of heat-shrink tubing. I had already done this on the first MPU, but on this one, I had to double it up. Overall, it works; the hold function and sound are still an issue. Plus a few other minor things here and there. Thanks Have a good weekend. Sorry, I can't seem to reduce the video size.

Good evening. I'm just giving an update. Regarding the stuck HOLD switch, I replaced the 4049 chip, but it didn't fix the problem. I tested all the diodes in the matrix; they're OK. The capacitor bank is OK. This switch is either on position 9 or 10. I'm going to retest this entire area. Otherwise, I might have to replace IC4. Hold coincé.mp4

Hello No, I can confirm, the coil is broken. I searched online, and 30 ohms is unknown. Well, maybe with some adaptation... Or, I could have it rebuilt. But the price won't be good, that's for sure. Thanks

thankyou ever so much

Here you go. I also converted it to run on MFME 20.1. topgear1280dx.zip

I have used a resistor before and it worked fine but less volume, if he is getting hiss I guess the speaker coil is fine, maybe ohm check the speaker or put a couple of volts across it

These speakers are practically impossible to find unless you are lucky enough to find a "new old stock " speaker or a second hand one . Bob isn't there a way to create 30ohms on a speaker with less ohms using resistors ?

I need this DX LAYOUT and early v ROMS (basically this link downloaded and emailed if poss to me or is it here on the mecca????? its TOP GEAR and this one seems to be the 3 pound version . i have the real machine but its the 4 pound. i love my machine and wanted to see the differences thanks and regards j sharpe showreels4u@hotmail.com

Hi , it's VenumX here from over at DesertIslandFruits.... I just came here to check things out, if its still somewhat active here, or for some inspiration..... Have a fun weekend!

Does the speaker actually measure 30 Ohms (or near)? They are difficult to find!

Hello Regarding the sound, I do have 15V, but the speaker is dead. I connected a small speaker; I get some hiss but no beep. A 30-ohm speaker isn't going to be easy to find. 🙄 I'll keep looking and try to sort things out. Thanks.

Whoooo - oooo - ooo 👻 Better (absurdly) late than never! Incoming shortly. (Probably not worth the wait lol)

Wow! Just seen this. What an absolute gem of a machine. Good luck - would be lovely to see the old girl in action.

Hello. I'll take a look at all of that. Thank you.

For the sound it's worth checking that you're seeing the 15v on the collector of T11, if you haven't already. IC3 only delivers the basic sound bleeps, the main sounds come from IC2. Not sure which one supplies the error sounds? For the Hold button it's possibly one of the associated diodes in the switch matrix unless it's affecting other switches you may not have noticed yet. In that case it could be IC22 or one of the caps C24-28 going short. It's quite easy to fault.

Nice result and worth pursuing for such a nice old game

Good evening. Three problems remain to be solved. 1) The sound 2) The display 3) The hold function on the second reel I'll tackle them one by one. The sound: I replaced T11; no improvement. I'll look into IC19 and IC3. Have a good evening.

I am a new member and newbke to this, I am looking to start by fruit machine roms to my handheld powkiddy a12, could be possible? I hope I can custom it over time
