Kev, Being a fellow 9100 user, I'm interested in solving the signature problem too. I'm new to the TechTools list and I may be covering stuff you guys have been over before and be stating the blindingly obvious, but here goes... If the 9100 does in fact use a CRC algorithm, then there are only so many polynomials that are useful. As a start, trying out CRC-12, CRC-16 and CRC-CCITT that are all 16-bit orientated polynomials might yeild a match with what the 9100 generates. As far as I know, the pods themselves do the signatures in the 9010 configuration. Here, one would think a disassembly of the pod ROM would yield what we need or failing that a simple driver in MAME that runs the pod code would do the trick? Regards, Paul. Kev wrote:
Kev has raised a good point about the lack of 9100 orientated info around.. plenty of 9010, but as any good 9100 owner would know, the rom signatures do differ..
I have a stack of sigs taken from a whole host of pcbs, all on some rather battle-worn notepads that i do need to type up and put in a printable/readable format...
I seem to remember John saying somethign about a fluke resource on his site, but the exact details escape me this minute..
