[rescue] Anyone know the encoding on the older IDPROMs?

[Neill Griffin]

Hi, at least for some of the early models the Serial #, HostID and MAC 
address are determined by defined offsets from the converted PROM ID code.

I had enough original ClassicXs and an SS10 and some other published 
information (ELC) to determine these offset values but unfortunately 
none of my IPCs or lone IPX had original values.

If anyone has any original Serial #/MAC data for the IPC or IPX or other 
models then these offsets could be determined.
