Does anyone have the pinout of the INTERNAL connector on the Apple Super
Serial ][ card? I found one without the cable. I know what the 25 pin
connector pinout is, but I need to get from one to the other.
I did google it, but I could not find the right pinout. Probably using a
wrong term or two.
Thanks,
Kelly

I would like to get these from you to add to the archives
on bitsavers. I currently have nothing on Norsk Data.

Maybe there is a "California Triangle" where all sorts of old computers
are lost. I'll bet the focus is somewhere near Sellam's warehouse.
An even better idea would be a "computer maze". In the Midwest they
have crop mazes where the farmer mows a path through the corn field to
entertain the city folks, who wander around.
Sellam could have a computer warehouse maze and we could all wander
around looking for lost computers!!

Just to let folks know that the QLink server re-implementation is going
well. At present, the following is working:
X.25 packet sequence simulation
Initial disk reset handshake
Read account and code off disk
If match, validate disk with new code and go to welcome text
If not, bring up dialog and ask user for screen name, with erro
checking. Add user, hook account code, and validate disk
Show welcome text and await F5 to go to Main Menu
Allow user to select any of the areas on the main menu
For People Connection, allow access to any public or private room,
ignore, de-ignore users, change rooms, change to another area, quit,
send or receive email.
For the other areas, show initial menu, and allow change to other areas,
email, or leave.
When a user gets mail, the "You've got mail" icon shows on their screen.
The server implements the required packet based sliding window protocol
and handles handshaking.
I'm working on adding online messages (IMs), and the Auditorium room,
then the file areas (will gateway to FTP/HTTP sites)
If there is interest, I can provide more details on-list or off-list.

[somehow this question makes me think of sex]
Does anyone have experience re-lubricating 9-track tapes?
I have some old 9-track 1/2" tapes which appear to be in good shape. I
baked them but they end up squeeking in the drive and eventually the
drive says "tape stuck".
After reading this
http://www.ukoln.ac.uk/services/elib/papers/supporting/pdf/p2.pdf
I think the tape needs to be re-lubricated. Once document I found made
a cavalier reference to using a silicone based libricant (which is what
made me think of astroglide :-) but it didn't give any details.
silicone = organosilicon polymer used in lubricants
http://www.wcaslab.com/tech/silicone.htm
astroglide = well, you figure it out
www.astroglide.com
anyone have any experience with this? it seems like something to be
done with great care...
-brad
ps: the astroglide reference is just there for humor sake. I'm sure there
is a more appropriate industrial grade lubricant used on tapes.
Needs to scan down to tv freqs (15.75khz) or close.
Would consider an early large EGA monitor also, if any
were made. BNC connections is ok. VGA is largely ruled
out because I'm looking to use it with digital
outputs.

I put some information I've accumulated up on my web space. It's at
<http://www.io.com/~trag> and look for the folder labeled
"Floppy_Circuits". It's uploading at this moment (11am CDT) so it
may be an hour or two from now before it's all up there.
There are data sheets for the WD37C65C, WD37C65+ and WD92C32 in PDF.
I also uploaded a scan of the National Semiconductor DP8473 datasheet
as a series of JPEGs. If someone has that one as a PDF I'd love to
get it in that more convenient format.
The most interesting bit is the "Floppy Disk Data Separator Design
Guide". This was included in the sales/information packet for the
DP8473. It's 28 pages of information on how to design a data
separator. Again, this is a collection of JPEGs.
It's a little inconvenient to read on screen because I scanned it at
150dpi (so a 100% image is quite large) but when I tried 72 dpi it
was too hard to read. The characters were chunky/incomplete at 72
dpi. The print in the actual booklet is rather small. 150 dpi was
the lowest resolution that led to readable characters without
eyestrain.
I've accumulated this stuff because I would like to clone the
external floppy drive for the Outbound Model 125 Laptop, but I'm not
actively working on this project yet, so don't have any questions for
the list at this time (unless someone knows an affordable source
(~$.50 ea.) of WD92C32s). I hope this information is helpful.

Re: "My problem with HP scanners isn't with the hardware -- it's usually
quite good -- but with the TWAIN driver and/or scanning software you have to
use. My preservation work involves scanning a lot of silkscreened material,
like software box covers and magazine ads, and I've found that the best way
to deal with that is to use the scanner software's built-in de-screening
process -- except, unless I'm missing something, HP's software doesn't have
any."
The software for the high-end HP scanners has descreening, although I'm not
sure about the low-end or all-in-one multifunction units.
On the 5470/5490 that I was discussing, the software is "HP PrecisionScan
Pro 3.1" and the descreen option is under "Advanced". Now as to how well it
works, that is a bit subjective, but the option is present.
