At the Ft. Tuthill swapmeet last weekend in Flagstaff, AZ, I rescued an
old Monroe Model 1 Electric Adding Calculator - 100 key panel, moving
carriage with number drums behind windows - you get the picture.
Since I am not at all interested in Yet Another Hobby, I thought I'd
offer this to the List first, as I know there are some of you who love
and collect these old babies.
Cosmetically it is quite good, needs cleaning and touch-up; mechanically
I am rather loath to fire it up, but all the knobs and keys seem to work,
the carriage moves with both the side lever and the t-handled knob at the
bottom of the keyboard, nothing seems gummed or jammed.
I would like to get some small amount for it, and I will be pleased to
pack and ship, weight will be about 15-20lb packed for the road from zip
95971. I will also be happy to send pix of it to you.
Send offers to me privately please, not to the List, this is mostly Off
Topic...

Who is <edick(a)idcomm.com>?
S/he/it appears to have Klez on their computer, and
CLASSICCMP <CLASSICCMP(a)trailing-edge.com>
is one of the bogus return addresses that it is affixing to its outgoing
crap.
Probably putting MINE on some, also!
PLEASE, download and run the Klez removal tool from Symantec at:

It sure is nice to run PINE on a shell account - total immunity to all of
the Outhouse crap.

I just found a great set of books online and ordered them
right away. The books are a 1962, first edition set,
published by Howard W. Sams called "Computer Basics".
VOL I: INTRODUCTION TO ANALOG COMPUTERS
VOL II: ANALOG COMPUTERS, MATHEMATICS AND CIRCUITRY
VOL III: DIGITAL COMPUTERS MATH AND CIRCUITRY
VOL IV: STORAGE AND LOGIC CIRCUITRY
VOL V: COMPUTER ORGANIZATION, PROGRAMMING AND MAINTANANCE
The first two volumes are also being auctioned off on eBay
right now and there are some pictures.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1551960033
The surprising thing is that I didn't find these books
on BookFinder.com. I found them on Barnes and Nobles website
(www.bn.com) under their "out of print" section.
While I was looking around also I came across this interesting
sounding book, but decided not to buy it.
Basics of Digital Computer Programming, John S. Murphy,
John F. Rider Publisher Inc. 1964 115 pgs.
Illustrated throughout with diagrams and charts.
Book # m840 Price: US$ 5.00

Does anyone have any spare WD-1000, WD-1001, or related disk controllers,
or documentation on them?
These are *not* ISA bus cards, they have a parallel interface to a host,
and control up to four 5.25-inch Winchester disk drives using the ST-506
or ST-412 interface. (Some models supported older 8-inch drives as well).
They use the Signetics 8X300 or 8X305 processor, WD-1100 series support
chips, and firmware in bipolar PROMs.
Thanks,
Eric

That is the stuff. I real don't recommend eating it. Some
come in colored crystals. This will tell you when it needs
to be regenerated. This can't be done while in the plastic
stuff but you can remove it and put it into a metal pan.
Put this in the oven ( I forget the temperature but
I'm sure a web search will find the right info ).
I forget the temperature but when it cools, it is back
to a bluish ( slightly brown from the heat ) color, it is
ready to use again. If it is pink, it has absorbed too much
water and won't do much.

Hi
Sitting in the tube, they should last for 1000's of
years. Moisture is about the only problem. Keep them
in a zip-loc with a packet a silca-gel and they will
out live you and your grandchildren's grandchildren.
Any temperature that a human can live in will have
virtually no effect on them.

If these are NOS and not test pulls, they should all be
functional. No need to test them unless you just feel
the urge.

-IBM 8bit ISA serial/parallel card with NS16450N uart, from an AT (Free)
-WDC 8/16 bit ISA 256K VGA card (Free)
-2 fan trays with fans from a DEC R400X DSSI expansion chassis.... these
are the same as the ones in any BA440 chassis right? ($10.00 both)
-1 power supply from DEC R400X DSSI expansion chassis. I assume this os
also the same as for the BA440. ($20)
-Kensington System Saver Mac, this is for a Plus, SE, etc. It's in
great shape. ($15.00)
-SCO Open Desktop 2.0.0 on QIC tape. I tried installing it, and I think
I had a bad tape drive.... NT wouldn't see the drive either. I picked
it up used but the tape had never been opened until I opened it. It is
in the original box with all manuals and license card. ($5.00)
-2 Belkin narrow centronics style 6 foot scsi cables and a no-name
terminator of some kind, probably passsive. All in new condition. ($10.00)

I have a lead on a Bull DPS-700 mini/mainframe computer available near
Paris for a very short time.
Unfortunately I cannot rescue it, any takers?

Time to check my book case... I have a few copies that visually look like
that pic, I wonder if any are v1.1... maybe I'll get lucky and can hock
one to buy the new CD burner I want.

Hi all,
My prized laser printer, a Panasonic KXP4400, has just decided that the
drum needs changing. I've put it into Service Mode and the drum pagecounter
is only 2800; the drum is supposed to last 6000 sheets. I've come to the
conclusion that the printer thinks the waste toner tank on the side of the
OPC mech needs replacing. The OPC drum (the green roller) is fine; it's been
printing OK for a while. Anyone know how to remove and empty the waste toner
tank? To put it bluntly, I'm too cheap to buy a ?70 OPC drum when all that's
wrong with the one I've got is a full waste toner tank!
Thanks.
