Just completed a board which made me smile. Came in with the usual full service needed, so once that was done it was switch on time. Pretty much dead so checking the RESET which was good it was out with the RAM. With my spare test board it fired straight up and then using my new chip tester showed one of the RAM chips was knackered.👍 The other one was good and yes I did try it with another just to confirm it ran properly in the board. So now it was time to run through all the tests before going into the Cabaret machine for a soak test. First all triacs were firing, next all switches, sound working, alpha good, reels good......hmm no lamps! Inspected the board again and couldn't believe I didn't see this the first time. Looks like the plumber's been here! Once that was removed all the vias and the pads were missing on both sides. After a bit of patching, new rivets and lots of patience I arrived at this. With a new transistor in place all lamps were now correct.

Early electro mechanical machines were 2p play, A maximum 10p in cash payouts and allowed a 25p ''Gold Award'' in the form of a single none replayble token which could only be redeemed over the pub bar for goods (Beer,Cigs etc). The maximum cash was only 10p but as they were 2p play they could payout 24p in replayble tokens which is why so many different versions and size of tokens in various values are still found today. The 6p token would be payout out in 4 tokens to make up the 24p top token win and found to be a better option than the single none replayble 25p token. It was passed by the gaming board in around 1973 that the 25p gold award could be made into replayble tokens and when the 5p token came into use. After 5p tokens the 10p token then the 20p token.

"Soldering by Stevie Wonder", as I once saw somebody had written on a job sheet...

Solved. The chips arrived today, so I popped one in and powered up the machine. Sound restored. I think the other board i bought had a sound fault, so I am going to fix and test with the lucky strike roms. Then I have a spare. Is it possible to copy the epproms to make a duplicate spare game card?

I bought them because they have the diodes in so are to replace all the holders on the red Dwarf project as they all are broken on the reels! I can confirm these holders DO NOT come with bulbs! Blue ones without the diodes I bought during lockdown DID have the bulbs!

If you go to notes in and select so it says ready for note you should be able to allow or inhibit notes with the RH2 button (possibly 50p start)

LOL, love it.

Thanks for taking the time to check, I think they are the correct one's But I just placed the order from Farnell yesterday! Thanks Ronnie
