hi all.. 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.. i need reminding.. where are they, how can i add to them, and would there be a html version instead of just a directory style listing? just an idea... Andy
