The MVS scans for MPE can be found here, and shows all the proper jumper settings.I've been working on trying to convert a PROG BK1 and CHA 256 to Money Puzzle Exchanger.
Since the CHA256 board was barely documented, and I was having some graphics and sound issues I spent some time with a multimeter and figured out what all the jumpers are for. here are the results:
If using 27c010 for M1
J2, J3 - jumped
J1, J4 - open
If using 27c301 for M1
J1, J4 - jumped
J2, J3 - open
If the Largest C-ROM is a 27c322
J9, J10 - jumped
J5, J6, J7, J8 - open
If the Largest C-ROM is a 27c160
J7, J8 - jumped
J5, J6, J9, J10 - open
If the Largest C-ROM is a 27c800
J5, J6 - jumped
J7, J8, J9, J10 - open
If C1 and C2 are 27C322
J11 - jumped
R1 - open
...if smaller do the opposite
...if empty both can be open
If C3 and C4 are 27C322
J12 - jumped
R2 - open
...if smaller do the opposite
...if empty both can be open
If C5 and C6 are 27C322
J13 - jumped
R3 - open
...if smaller do the opposite
...if empty both can be open
If C7 and C8 are 27C322
J14 - jumped
R4 - open
...if smaller do the opposite
...if empty both can be open
Based on other conversions I originally had J11 and R2 jumped but I swapped it to R1 and R2 after I figured out their function since I'm using a 160 for C1/C2 and a 800 for C3/C4 and now my graphics are perfect. arguably you could set the jumpers for 322 across the board and just condense all of the C-ROMs to 322s. I thought for sure some of those jumpers were for the S1 ROM but none of them touch it.
I still have problems with the music but at least I'm confident that the jumpers on the CHA board are 100% correct now.
The PROG BK1 is pretty well documented on the ngdev wiki but there are 4 or 5 jumpers near the bottom that I don't think are covered. so either that is related to my sound issue, or maybe I have a bad burn or cold solder joint on one of my chips.
If anyone has a Bootleg or Conversion Money Puzzle I'd love to see pictures of the PCB.
