    I've got a card flipper unit I saved many years ago from when Arcadia, Ryde scrapped their Flip A Note. It's a stepper with a single opto. It starts with a blank card and then repeats 1 to 9 seven times. The opto is triggered on the 9 card just before the blank card. I'll post some pics later.
  5. Well, I didn't think it would ever happen but the notorious and elusive Big Fifty is now part of the collection! There's plenty of work to be done to bring this gem back to some sort of former glory so stay tuned!

    More progress! I've sorted out the worst of the battery damage but there's still loads of logic ICs to replace on the bottom right corner. Still, she's working again for now, complete with a coin cell backup battery solution!

    Thanks for the offer, what's the part number of those units? For the time being, I lifted some working units from a spare display board that happened to have the same "colour bin" segments.

    Any chance of a PCP Love-o-meter so we can see how close we are? 😄

    Excellent, I'm looking forward to seeing the gameplay on this one!
  11. I'm sure you could do better, I wrote that over 16 years ago using VB6 and very basic graphics techniques! The gameplay in my sim is a combination of observation and guesswork, nothing more!! I never did get around to adding game sound effects but I'm glad you still found it interesting! Good luck with your sim.

    Crackerpot would have joined in too but not enough space!!

    At last, I've made a space for it next to the others!

    A good video will happen at some point, probably once I have it positioned alongside its siblings! Also, people have previously said that if you run out of credits mid streak then adding more causes a "continue yes/no" before being progressing to the next "£2 yes/no"; this doesn't seem to be the case. Adding more credits just allows you to continue where you left off. A different software version to what people remember, perhaps? I'll try to capture it on video...

    I've not had the chance to do any more work on this yet but a 10 minute play did result in a nice £26 streak...

    It's slow progress but the Sentinel mech has now been cleaned and routing issues have been addressed. Someone else's attempt at fixing the acceptor gate, now fixed by just straightening the left of the spring: The leaf spring in the separator had also been messed around with, making the gate too stiff for the solenoid to move. Fixed by reshaping the spring to match a good one! After all that, acceptance is still very poor on any coin other than the old 50p, probably just down to wear and tear. Time for recalibration I think!

    Castle - 15 mins of fame, unforgotten.

    You might have noticed that the sound is a bit iffy, for some reason the machine keeps beeping about once a second and it interrupts the gameplay sounds. I'm currently working with Mr. P to resolve this!

    Either that or it's bloody well haunted!!

    Despite the battery damage to the MPU, the RAM chip is happily holding it's data from one day to the next. The only unusual thing with that is that I snipped the battery off a few days ago... How long do RAM chips normally hold data with no power?!

    Just go for it and enjoy learning the gameplay!

    Yeah, a video would be great. My Big Fifty was made in October 1987. In fact, most Castle machines were made in 1987!

    Investigating some snipped wires behind the meter panel... Out comes the panel which reveals the final resting place of a long dead family of spiders... A better look at the wiring. I think the snipped ones are just unused ground connections for the door switches. No idea why they were cut though... Bonus! It seems that the spiders were the guardians of a hidden treasure trove. Well, 50 pence worth of old tens...

    Cheers, the price was a bit of a sting at £420 considering the condition of the MPU but I can handle that! And yes, the relief when it was finally in the house was immeasurable!!!

    Power supply looks good, nothing to do here except tighten a fuse holder and blow some cobwebs out.
