Some '96 GM's still support the old ALDL communications on
unused pins of the OBDII connector.  A subset(?) of the J1850
commands are available through these pins, although at a lower
bandwidth than the OBDII bus.  We have some info on this
available on our obdii site at www.obdii.com  - and, if I can
insert a shameless plug, a nice DOS-based OBDII GM scantool.

Some '96 f-bodies have the same dual-bus setup. ALDL appears to
have disappeared by '97.  Also, some '95's support the J1850 bus
in addition to ALDL. Sort of a transition period.
