Quoted from Meldenhut:
Have you considered buying the Gen2 evo board, driver board and power board from
I would bet that it was just Zacc gen2 hardware in the original
Then you would just need to put the rom in it
I have not considered this as an option just yet, but will keep this in mind.
I want to quote a message I received from my helpful Italian friend. This is why I have not considered this just yet... This conversation was in relation to the sound board which he is currently working on.
"yes, but... we have a problem for your thunder man. I realized that the card used on that pinball machine is very similar to the Zaccaria, however the printed circuit is different. The t.m. mounts 2 eprom 2764 which have 4 more pins than the original 2532. this means that the board is necessarily different. Without the wiring diagrams, it will not be easy to make the changes. On the CPU board instead, there is already the predisposition for the 2764 and it should be simpler."
This is why he has asked me to see if I can provide some detailed photos of the boards especially in the eprom area.
Of course I'm not dismissing any opinions and suggestions here, so thank you for your suggestion Meldenhut, however because I know the history of his work with Bell Games I'm happy to wait until he has all the info he needs to recreate the boards. If he cannot then of course purchasing from Pinballsolutions.eu will be the next option.
I'm in no rush, I'm poor after my last purchase and I still need to finish my Cobra project before I get started on Thunder Man.
