The complete thing is scanned and indexed (minimally) at
wps.com/projects/LGP-21/Documentation/LGP-21-Maintenance-Training-Manual/
I'm not completely happy with the index, but URLs etc won't change when
I fix it. It's not entirely obvious that to see page 6-36, not in the
index, for instance, that you can get there by clicking NEXT PAGE on
page 6-35. No matter, the scanning is done other than to fix a few
crooked pages.
If anyone wants a copy send me SASE that'll hold a CD-R and I'll save
you the trouble of downloading.
