Ahhhh. Ok, that makes sense. This begs the question, does anyone need the
thing? I sure can't use it.

That's an interesting idea. Form a club centered around the list,
maintain an online bank account, take pre-auction votes on maximum
bids for a particular lot, and have a person local to each relevant
auction go on behalf of the group.

I've made contact with a guy who's scanned 20,046 pages of the
docs listed below, at 300 to 400 DPI. He first told me about the
UCSD p-System docs he'd scanned. Below the list is his description
of the process he followed.
I'm planning to get a copy of what he has and burn it to CD-R.
Does anyone else have an interest in these docs, or have any
ideas about distribution without massive copyright violation?

> What sort of process did you follow? What sort of devices?
As far as the process, I scanned a manual in and checked to make sure
all the pages were there. If they weren't, I'd scan the pages that
didn't make it, and go through all the pages again. I'll admit this is a
little anal, but better safe than sorry. (When you're using a lot of
shell scripts, you never know if you accidently deleted a page with an
"mv" command.) When all the pages where there, I'd go through the manual
one more time to check for general quality (no folded corners, no torn
pages, etc.) If all was good, the manual would be moved to the directory
that would be the root directory of my CD-ROM. That's pretty much it.
The big manuals of more than 1000 pages really sucked, because I'd
generally have to make 3 or more passes to get those completely correct.
If I was going to do it again, I'd probably break the larger manuals
into smaller chunks to avoid this problem.
One thing that made the whole process a lot easier was the netpbm
utilities. I wrote a script to convert the manuals from ~2500x3300 TIFs
to ~500x600 GIFs. My machine takes about 2 seconds to process a 300-400
DPI TIF, but only a fraction of a second for a 75 DPI GIF. I'd run my
script, then do something else for a while. When it was done, I could
flip through the GIFs with GQview and inspect about 2-4 pages per
second. That saved a lot of time.
I assume that, by "devices", you mean what type of scanners I used. I
started with an HP 6350cse (with ADF) that I bought for this very
purpose. However, having never owned a scanner before, I was a little
disappointed with how slow the "fast" scanners are. Fortunately, imaging
is an integral part of the software my company sells and, as luck would
have it, we were demoing a new scanner from Fujitsu. This thing
literally does 60 pages/min at 300 dpi - *both* sides. It's about half
that fast at 400 dpi, which I had to use for the IC databooks to get the
fine print. Needless to say, I did most of my scanning on that.
By the way, to date, I've processed 20046 pages. I'm kinda burned out,
though, so it'll be a while before I do any more.

I thought I'd seen them (N-BNC) in the CPC catalogue, but when I looked
just now, I found N-to-anything_but_BNC for around ?1.50. Maybe I was
thinking of Farnell (who ain't so cheap). Cirkit sell them for ?2.69.
Ouch! I've just found the price in the Electrospeed catalogue (?8). I
got most of mine from older network installations, where people had added
thinnet to (or in some places, instead of) original thick yellow ether.
Older N-series tranceivers often got reused in such situations, I find.
Electrospeed still claim to sell coax taps for ?22, and assorted
transceiver adaptors (N-series ?15, straight single BNC ?12, dual (T) BNC
?14).

Bill and everybody else,
I'm pleased with that dongle thing, I used it to transfer the stuff
first with a HVF explorer to place the files in HFS image disk w/
raw data fork selected. Then moved stuff between pc emulating a Mac
(basilisk II, freeware) to real Mac. Far easier than all those disks
sneakernet and I didn't have correct scsi cable for my PCI controller
(HD connector to centronics needed). Nearly 60 MB moved at snail's
pace due to emulation but does work as it should be which is fine
with me. :-)
All this stuff is freeware or demoware, just the same it earned their
worth for me.
Treashing around story:
Took me hours searching because the pc-mac sharing or conversion
utilities via network (examples: DAVE, MacPclan are over $120 US or
more which will break my limited canadian budget and very leery
about asking so much of my personal details before obtaining demo
programs. When I saw a webpage suggesting Basilisk II, I pounced on
it like a cat. Then more hours on basilisk II/sharing figuring out
and RTFM'ing lot of stuff to get everything to work but I succeeded!
Tip: Somewhere in that netscape/IE on peecee is screwing the pooch
on hqx, before clicking that ok button to download, change .hqx for
.txt. When d/l done, rename it back. That works. I still don't
figure out why HVF explorer doesn't work on mac formatted disks but
basilisk II will read/write these 1.44 disks, remember peecees can't
deal with 400K/800K due to FD controller issues. That is what real
Mac I moving stuff to is for.
Amazing how small that Basilisk II is and fairly stable, nothing left
out to make mac emulation to work and 100% lookalike. Funny, that
ran like scalded rabbit on duron 800. It stutters sometimes because
both HFS images were on old 540MB hd, other than that, it crackles.
Bill, Thanks for that dongle!!
Wizard with big smile.
FYI: Basilisk II is ported to linux, Amiga, win9x/NT/2000 and one
other I forgot. Only supports 512K or 1MB Mac roms, everything you
need are bundled in one download except for HVF explorer. Download
that 11MB PDF basilisk II manual is a must as it has new info in it,
far more info than what I have seen on webpages. This file does
contains vital info that is required to get started and installing
OS, plus at least one extension has to be OFF.
Does anyone have handy the switch settings for DEC PDP-11/44
memory boards? I have a collection of third-party boards
(nat. semi and standard memories) but no documentation on
them.
I suspect they use the same dip settings as DEC MS11-xx (M8743)
boards (of which I also have a few but no docos).
I'm also looking for DZ11 (M7819) IRQ/CSR switch settings.
Thanks!

Yes, but the standard method of terminating a single (isolated) point is to
use ONE terminator (maybe not for Vaxstations :-)).

I've not looked that closely at the internal circuitry of a transceiver,
but I can assure you that that's NOT what happens with any transceiver I've
tried. Having no terminator at all does indeed make many transceivers
believe there are constant collisions, but I've always found one to be
enough to prevent that, providing it's directly on the transceiver. The
official method for SGIs is to put a microtransceiver with a single
terminator on the AUI connector.

Yes, and it should also be around 1/2 - 1 watt. Many terminators use 1/4
watt and get away with it, but the nominal voltage is 10V (and hence from
P=V^2/R, and allowing a 50% duty cycle, you want 1W).

Yes, they are different, and I *think* that's the right way round :-)

I'm pretty much full here too...but there are some surplus
facilities nearby that aren't really open to the public, but that I
have access to. Lots of larger DEC stuff (a lot of VAX6000s) shows up
there.
Maybe we should set up such a thing. There would be a number of
things to arrange to keep things running smoothly, but I think it
could be done.
