  1. There were bits added to the emulator over time as various Black Box oddities emerged, if you have the schematic for this game it will tell us what the aux boards are connected to and if they are supported in the emulator. The later Black Box games had some sort of security device in them, not sure how they integrated with the MPU though. Address #5000 is not an auxillary board, it's the 550 transistors on the main output board.
  2. Just add a standard lamp matrix (all) to your layout. If you have a schematic I can tell you what numbers the lamps are mapped to.
  3. Hi danno, I am deperated looking for JPM Step Up schematic drawing, can you please help me.




  4. As Bob said i would start with the 2 pots, then check the 4 bridge diodes as these can go open circuit.
  5. Hi Dave, It was the Apple, Shamrock and Lemon I was after mainly, thanks.
  6. Hi Ron, I don't suppose by some miracle you still have the photos of these symbols please?
  7. Looks similar to Supermatch Deluxe Steve but in newer Cab
  8. This looks the same as a JPM Step Up, I put the schematics on here a while ago.
  9. Thinking about it, when I put the PLC in a electro it just used inputs so probably not relevent here,
  10. Hmm, All along time ago now. Don't over think it, there may be many combinations for all the fruit symbols etc but the MPU isn't interested in that. All there will be is a handful of inputs to the MPU. A couple of switches is all you probably need, one for each input. You probably don't even need to look at the reel deck. There may be 10 different combinations on the reels to pay 20p for example but the MPU will only need one input. (one switch will cover all 20p combinations). On the Electro decks with the optos they count the positions and increment the RAM, the MPU then uses a look up table to determine wins. This looks to be using studs so it will report to the MPU relevent to it's position.

    Bob, Do we have ROM's for Hi-Lights? I'll try them in the Emulator if we have and see if it's there.

    Isn't it machine specific? Which indicates it would be on the game ROMS?
  13. In powder coating it's a type of Hammer finish. Although Hammer finish is usually paired with a full gloss finish. This is like a Satin/Hammer finish.
