The problem is with the pictures and diagrams. Now, if you have tools which
make this a straightforward task achievable in a day or so for the 5k or so
pages ultimately involved, then maybe you're the one for the job, but
beware! It's never as simple as it looks. BTW, I don't think GIF is an
efficient way to represent LINE ART, which is what generally is involved in
illustrations and schematic diagrams.

Doesn't that say something? Like use plain ASCII if at all possible :-)
Actually, Ghostscript should be able to drive (or be modified to drive)
at least one of your printers. And it will read/print at least Level 1
postscript files.

But, and this applies to text as well, once you've
printed them out and
scanned them back in again, you've lost that structure. The scanner
produces a bitmap (probably a slightly distorted bitmap as noting is
perfect). It is _very_ difficult to automatically recover that structure
(would you like to write a program that analyses a bitmap and finds
component symbols in it?)
No, it is not difficult at all. Just go out and purchase (!?!) one of the
many pieces of software that does the trick. Sure, not mainstream, but
they are out there. They do a pretty good job, too. Not too much
different from OCR...

Hey Bill! Haven't read you for quite awhile. Some of us were wondering
where you'd gone. You musta been out physically dragging home that elusive
IBM 360 you've been lusting after ;) Welcome back!
Regards, Chris

I left ANS/UUnet about a month back, before the whole thing goes under.
No, I did not find any neato IBM hardware while gone. In fact, no
computer hardware at all, really (except for the kind soul that sent the
IRIX stuff and 3090 book - payment goes out shortly.) Lately, the fun has
been with radio and radar acquisitions - most notably one of the surface
search sets from (probably) the U.S.S. California, and some 1930s radio gear
from the destroyer tender U.S.S. Altair (OK, it's
probably the
furthest stretch yet to being on the topic of classic computers).
Meanwhile, my Sportster died (what a suprise), so I am using one of these
classic IBM 7855-10s at 9600 bps, and not having fun doing so...
