Bell and Howell Gm CD

[peter paul fenske]

Hi Guys

I was wondering if anyone on the net knows anything of
the GM dealer protocol used in the Gm inhouse CDS.

I have just acquired a full set with all catalogs, vehicles tsbs
and ecm updates but without spending about 10K or so this
stuff is useless. Anyway  this is a hobby!

Does anyone know about the CD protocol. Building something
to read em is really not that difficuilt 

Thanks guys: peter
