Hi
If any of you think that I *invented* Pearls... not true at all. Back in 1999 Jerry did it. Here is his post from the past to set the record straight. His comments on this exercise are well worth remembering

Compendium - Finally!
Finally, after days of effort
and probably killing several trees in the process, I finished putting together
the initial version of my personal R-390A Paper Compendium, sort of a giant
hard copy FAQ. Regressing from electronic filing to paper may seem weird, but I
have found that electronic archives, while a great asset, are a time-consuming
pain to keep going back to repeatedly. I found I was constantly hunting for
stuff I just knew I had read "somewhere" in a post on this reflector,
and hated to waste bandwidth by revisiting the question on the list. So I set
out on a quest to glean the most (IMHO) directly useful posts over the past
year or so, with the idea of building myself a workbench-handy reference
containing the best of the best from all you wizards out there.
Ended up printing about 300
posts, many several pages long, on my tired LaserJet 4L (it's little tongue is
still hanging out), arbitrarily categorizing everything, and putting it all
into a fat 3-inch 3-ring binder under the following subject categories:
ID/General Info (includes
historical stuff)
General Rebuilding
Schematics/Manuals
Main Chassis
Connectors/Cables
General Test & Alignment
Cleaning, Paint & Cosmetics
Meters
RF Deck
PTO
IF Deck
AF Deck
Line Voltage & Power Supply
Xtal Cal/BFO
TroubleshootingCabinets,
Cases, & Covers
Some of the categories get a bit fuzzy and overlap and
it was a definite pain to put together, but it's done now, and I will continue
to add to it by saving, printing,
and inserting what appear to me to be the most informative posts. I highly
recommend that R-390 semi-newbies (like me) do this drill if you can stand the
pain. It's amazing how much you will absorb and retain as you read and organize
all this stuff, a disk crash will have no effect on it, and it will be an
extremely handy addition to your workbench bookshelf.
