WTB WBA-20-SS acceptor head and some questions

[websherpa]

I have a Bally S6000 (Blazing 7's) that came out of a Canadian casino, and then it came back to Canada with a US WBA-12-SS USA 501-44 acceptor head (although I can see from other markings that it used to have a WBA-21-SS CAN 502-03).

I would like to convert it back to Canadian currency for easier loading up of credits. I happen to have a WBA-20-SS CAN EPROM handy.

My questions,

I can not just substitute the WBA-20 chip for the existing WBA-12 eprom chip without also changing the acceptor head and get access to Canadian $ bill acceptance, can I?  (Would I burn something out by trying it, or just get an error?)

Where can I possibly get a used WBA-20-SS CAN acceptor head (only), or WBA-21-SS CAN$ acceptor head and Eprom inexpensively (or to trade for my WBA-12-SS acceptor head and Eprom (old US bills only)?  How about a calibration paper, where can I get these and/or a test extenstion harness (for host to WBA) - or are their plans for building one (I am electronics tech savvy).

Thanks for any help you can give!

Hi Wayne,
  You need the wba20 or 21 head for it to work properly.  What version is your eprom?  I have some up to date eproms if you run into the need .

Thanks Wayne,(yes my name is Wayne also)
I am located in Brampton.

Thank you, small world, I am in Waterdown.  I'll look up the ROM number to check with you.  My challenge will be finding the right acceptor head.
