George's response was:

Does Diacom have and any idea about their massive following?  The latest
J.C. Witney catalog #586k (inside cover page) has an Auto Xray XP240 scanner
for $280 complete, no PC needed. The illustration shows a two line display
(32 characters). Interface cables are available for GM (king of autos), Ford
:-}, and that other car maker ... Chrysler for only $29 each.  I do not own
one, and I don't know anybody that owns one. I'd be willing to bet that it
works as advertised.

I neglected to tell you folks out in DIY FI land, what my true reason was
for wanting to read ALDL data.

Here's my confession. I have constructed a mid engine, rear wheel driven
sports car from scratch. The engine is a '85 PFI 3.8L Buick V6.  The plan is
to transmit the ALDl data to a dedicated PC, peramanently mounted in the car
and connected to a small VGA monitor. Software would convert the data to
usefull information that would be displayed on the monitor.  Boom, no
additional instruments needed and a wealth of data on demand. The car
(Bianca) was designed to house a PC.  Think of her as a streached
Lamborghini Contach with all the room and comfort of a full size '70's Olds.
Data logging would also be utilized. The PC would also control some BODY
functions. It's not that I'm to cheap to by Diacom or XP240 (I just might by
the XP240) but, if I'm going to make this work I need to get some type of
simple PC to ALDL communication established.

Any help on the software end would be much needed.

thanks'
