The pod does not do the Signatures, all the pods do is READ and WRITE (in both cases only a single BYTE at a time) and monitor status lines. Nothing else. The base deals with the data once it is read or written to the pod... John :-#)# At 04:13 PM 31/05/2002 -0700, Paul Swan wrote:
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.

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..
