ALDL interface circuit

[Chief]

I searched the archives and only found the GM ALDL interface schematic in
Tango format.  I have the file DB.SO1 but can't convert it.  Searched the
internet for a conversion utility to no avail. :-(

Is this available in some common format, pcx, gif, jpg or whatever?  If so,
could someone please mail it directly to me, point me to a web or ftp site?

Thanks very much.
