Thanks Nick, I've managed to get the sequence of each reel's symbols and I have pics all of reel 3's sensor holes although I haven't worked out yet how the binary representation is done. The main thing is it's noted that the same symbols don't match the same holes on the three reels. Getting good pics of the other two reels is nigh on impossible I reckon but I suspect that the physical reels are identical in their hole placement but the bands are obviously different hence the same symbols having different holes. If I can work out the binary on the last reel then it should be easy to transpose that to the other two and then map their symbols accordingly. I do love a challenge!

Updated the new romset with the code to remove the gamble limit. At this time the jackpot tune will play and auto collect at more than £100 on the roulette wheel. Original version: Changes made: At this time there is no code to reduce the pot back to £100 when the gamble win is higher. This is due to limited space for additional code. Next step is to try the new roms in a machine. The new rom set is attached. CCH120_STD_MOD.zip

Hi all, It's head scratching time again! I'm working on a board for Match it and the first thing I'm after is the wiring diagram for the machine (not the MPU). I can't find it on here so far but it could be lurking in some dark corner. It uses the 'slingshot' mech and has a feature to match one or both of the other reels by stepping a reel one postition at a time until it reaches the same symbol. Not having a machine to test it with I need to emulate this on my test rig. The reel positions are decided by holes in the reels which allow up to 5 sensors to be activated most likely in binary up to 20 (decimal) positions. All guess work at present but I'm getting some pics sent over of the reel holes per symbol so I should be able to confirm my thoughts. So far the board is now running but during testing in the machine the Match it feature continually stepped the reel ad infinitum. I suspected this could be a sensor problem and when the sensors and backplane arrived I noted there were two outputs not working due to the failed chip on the reel sensor backplane board. I now need to check that this feature is working but although I have a tester which selects any combination of the 5 outputs I still can't get the reel to stop. It could be I just don't know which bits need to be set as all I can see on my rig is the lamp pulsing which is equivalent to the slingshot solenoid on the machine and of course the changing sound. I can emulate a couple of wins with certain bits set so I know I'm almost there. Hope this all makes sense? There's not much info out there on these old techs but the more I delve into them I realise how clever the guys were that developed them. I just wish that they'd written more docs.

Well, just worked out that holes in the reel are incrementing in binary exactly like the studs do in the motor driven wiper mech. That makes it really easy to match the symbols on the reel bands to their binary equivalent. Just one thing that almost caught me was remembering the sensors are at the back so I'll have to mirror what I'm reading at the front.

Fantastic layout. Thanks for releasing these.

After some testing by @sulzerned on his machine we found that there were a couple of issues to address with the updated roms for the Cabaret 100 and more work is needed to refine. The issues experienced are the base roms that I used turned out to be a version for the 50p to provide 1x credit and 4x10p change. Then for some reason when the £100 Jackpot is won on the roulette wheel the machine pays out in 10p's 🙂 . The preferred version to use is 50p for 5x credits and of course to pay out the jackpot in 50p's. The previous version from the downloads section was labelled D16 which I now know is £100 Jackpot and 50p for 1x credit and 4x 10p change. I now have the correct program card from the Cabaret 100 that I have dumped and will use as the starting point to re apply the changes that I made previously. The new version is CCH12.0 which is the £100 Jackpot and 50p for 5x credits. Copy of these standard roms is attached, they were dumped from 3x 2532 EPROMS Cabaret 100 CCH120.zip
