Hi,
I've just noticed that we miss to add some picture of this board here !

Quoted from KenLayton:Haunted House is NOT on the list of supported machines.
Indeed, because Haunted House has NEVER used this type of board. This pinball use the evolved board (using 6502/6532 and NOT the 6530) with less populated components (no SC-01).
And about FPGA: it's by far easier to program this component using a very common USB adapter, than the CPU used by Pascal on his sounds boards. We just need that:
The CPU used Janin's boards is a very old chip (initially intended to be placed on LCD screen). This (no more in production) component need a special programmer and use a very specific protocol. The only programmer that can be found for that, need a parallel port (Centronics) that no more exist on modern PC.
