A short between ARDY and D0. I can see that messing things up... "ARDY Register A Ready (output, active High). The meaning of this signal depends on the mode of operation selected for Port A as follows: 1. Output mode: This signal goes active to indicate that the Port A output register has been loaded and the peripheral data bus is stable and ready for transfer to the peripheral device. 2. Input mode: This signal is active when the Port input register is empty and is ready to accept data from the peripheral device. 3. Bidirectional mode: This signal is active when data is available in the Port A output register for transfer to the peripheral device. In this mode, data is slot placed on the Port A data bus unless ASTB is active. 4. Control mode: This signal is disabled and forced to a Low state."

1986 Nifty 50. Loads more Barcrest games but no idea of dates. £4.80 JACKPOT era Jolly Joker The Nickelodean 1991 Big Bucks 1991 Cloud 999 Blue Moon Red Hot Roll Super Two (curved bottom glass) £6 JACKPOT era Super Streak Andy Capp Andy's Great Escape Viva Espana Viva Las Vegas,Six Lucky Las Vegas Adders & Ladders mpu4 Hyper Viper mpu4 Luxor Hot Rod Road Hog Exchanges Unlimited out before Adders & Ladders. Always thought it was the other way round lol. On conversions Juggler was a 5p Rock On. VFS Wheel of Fortune used to be an Instant Replay. Superwin by BWB was an Options Unlimited. Cashcade used to be an Adders and Ladders. Lucky Line by Associated Leisure was an ex Hi-lights Lucky Strike by Associated Leisure was an ex Spotlight. There were a few conversions from Nudges Unlimited to Golden Nudges,Silver Nudges,Noughts & Crosses,Shades Optimum. Too many to remember lol.

I think the remaining capacitors must be from RS European hub so it looks like Brexit is the cause of the delay, they will arrive when they arrive!!!

hello and welcome mr robot enjoy your stay

Hi, I posted 2 lists one was in 2001 and the other from 2008 both were from Barcrest when they were quite good at providing info. barcrest78-87.zip

No problem Mike, The timer shown is wired to minimum so really that is the least you want to have wired but I start generously with more studs than shown connected and if too much payout then reduce to the level that suits you. Electro's holds and nudges are the feature of their games and they need them working well to return great game play.

That blue/black wire should be to one side of the 50p lockout coil, check that it still has a 10p tube switch to operate the coil too. Hold nudge timer butchered as usual for the minimum % control on electro's The centre green wire is the 50v input circuit wire and connects to the inner ring of the board. The White/Orange should be the output wire to the holds and wired and linked to random studs down the right hand side of board. The White/Brown should be the output wire to the nudges and wired and linked to random studs down the left hand side of the board The board studs and two wiper arms will most probably need cleaning for best contact. The Super Start relies on not only the position of certain relays and cam switches but a good amount of hold studs wired, because hardly any are wired now will be the reason of little or no Super Starts. Here Pictured is a board from a hold nudge timer and you can see how the links have been wired on this board and this is minimal. Yellow arrowed is the 50v input to the solid centre ring. The Blue arrowed are the hold output to the hold relay, this setup has three links together near the top and one further down the right side. The Red arrowed are the nudge output to the nudge relay, this has one wired stud near the top and two linked further down the left side. At the start of the game the hold/nudge timer motor will stop start just the one time and in a millisecond at the same time to put a circuit through the timers centre ring. If the rotating wipers have stopped at that time on a live hold stud then the hold relays are activated, If they stop on a live Nudge stud then nudge relay activated. All the none wired studs are dead so when wipers stop on dead stud then no hold or nudges selected. Operators by removing the links from live studs decreased the odds of holds and nudges to virtually none and the results of their work is seen on this Two step today. So, For every wired stud becomes live and increases the chance of either hold or nudges. This timer has been link wired direct to the stud solder joints but like most timers easier to wire around the Orange arrowed outside contacts Do not however mix the wiring between the holds and nudges.

Thats great dave nice idea

As I'm doing this I'm going to make an electronic booklet for reference. 1st up is the control panel diagram. Control Unit.pdf

Cool find, so that answers where I must have got the list from and why there's only one for Barcrest, not other manufacturers. Although actually my list went up to 89....so i wonder if it was posted elsewhere and updated as the format is also different. Mine is dated 25 April whereas this post is 8 May so I must have got mine from before Captain Haddock's post but maybe Barcrest released info to others at around same time?

If you google barcrest games list mpu Mecca the original list is there that captain haddock posted years ago,the clubbers are in that and lucky lotto nick.

Well the two segments missing from the 7 seg display turned out to be two of the power resistors being open circuit. They were actually damaged which had broken the wire in the resistors. You can see the damage on the top, more than likely caused by boards piled on top of each other. I can't find these anywhere, they are 47R 2W with 10mm lead spacing so it could be a donor board job which is a shame. Another 'fault' showed itself as triac TR5 always on and I couldn't make out why as it was definitely being driven from IC4. I eventually found this by chance and it was due to switch 5 being in the OFF position!!!

Sorry this is the geeky side of me popping out, yeah the 1983 2p is actually rare(ish), as in I think 82 the "New" Pence was dropped and changed to "Two", so a fair amount were made but still rare as in 1983 had New Pence on it in error. Yeah ok I'll get my coat, its a new level of sad geeky shit...sorry 😆🙂

Jimmy might have a few for sale around the £100 mark or just under....

Most of my fading memory would be focused on machines, I had good times on. Namely JPM's in the early 80's, then Crests, back to JPM's in the 90's and Crests again until 2004. My memory starts on late EM machines with 50p jackpots, way upto 25 quid Maygays and JPM's. I'm sure there's a lot of folks who remember the classics, but not so much the test machines. And that can be tricky. As they were sited in random places, and recalling them isn't easy Example Maygay EPOCH machines such as Monte Carlo or Bust, or Maximum Overdrive (4 reel AWP) both 15 quid. BGT Millenium Bug. Those I can recall, as I played them a lot Then there was a Maygay EPOCH that had shields, 5 line win, 10 quid jackpot. It was a medieval theme. Seen it at Thomas amusements in Leicester Same place had an ACE machine (same cabinet as Pot of Gold) Called "5th Dimension" Black reels, with hidden fruits, that glowed. Quite unique. Also had a Barcode feature Random stuff like this, still floats around my head Statto

Not sure if I like the taste of humble pie or not but I did have a large slice today. I eventually found that one of the data lines was low and looking on the solder side spotted a bridge between pins 19 and 18 on IC4. Don't know why I didn't see it before as I always check with the microscope after putting in sockets. Not sure what's on pin 18, it's not mentioned on the diagram but with the chip in it brought the whole thing down. Of course I did start with the serial I/O chip first which was blameless but hey ho that's life! Now it all boots with IC4 in I'm happy, well sort of as there's now two segments not being driven on the 7 seg display.Roll on tomorrow.

Nifty fifty’s were converted super silvers that’s probably why it’s not on the list.

I bet Richie ain't as shiny as mine.

go to the bank

hello and a very warm welcome to you enjoy your stay

yeah, between us all we could fill in a lot of gaps ... ... they didn't mention this one but a cracker it looks ... what AL based Big Apple on? (saving a space in my lounge for one of these)
