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

Still not here yet! hoping in the next few weeks

Did it arrive ok, were you happy?

As they say... the end justifies the means.

A quick update, i thought i had got rid of this strange reset issue but alas i had not (well i have now). So running on the golden nudge it cart, 9 times out of ten when you got nudges it would work, however with its own nippy nudger cart it rarely would, normal gameplay fine but as soon as you nudged it would reset. Wiring between the two carts slightly different as it uses different lamp outputs for nudge feature and the coin lockout and one of the meters are swapped. Anyway by total accident i realised it was only when the four lamps in the nudge panel were flashing and you nudged it would reset, take the lamps out and it would be fine, now psu is ok all recapped and new regulator, 5.1v very steady but a 0.4v drop on the 15v (15.2v) when lamps flashing. I was only getting 8.6v across the 9.1v zener but that could well be within tolerance. At this point i cheated a little as the only 9.1v zener i have is a stud mount diode so i put an 8.2v zener in (i do recall Barcrest released some notes on MPU3 about changing the zener on low voltage sites, not that mine is low). It works fine now every time. So maybe it is an iffy zener transistor or resistor on the voltage sense circuit (i dont care now it works)

No, the congratulations are for you, the experts. I'll try to find the right diagram. Thank you. To be continued.

There are three different types of RESET circuit. There is pic of them in the downloads area somewhere and they are all different. Felicitations Lamiral.
