I agree with Aaron Finney's suggestions about using B/W "line art"
mode when possible, and the advantages of a 600 dpi laser printer
as opposed to 300 dpi. Also tinker with the JPEG compression settings,
you may be surprised how much space that will save, and how little
it will affect the images. Reload the saved images to examine the loss.
Yesterday I noticed that the latest version of an image thumbnailing
utility, ThumbsPlus, can save HTML versions of the thumbnailed
pages. This may be a very good way to organize your images for
the CD: it would make an HTML page, viewable in any browser, that
showed all the thumbnail versions of the images, and you could
click on any one to enlarge it.
See <http://www.tardis.ed.ac.uk/~itda/frames.html> where
two fellows have laboriously scanned, OCRed and converted to
Adobe Acrobat PDF files several documents including the Shugart
SA-800 floppy service manuals and several Terak docs. An 18-page
service manual with three-four pages of images is 262K.
I plan to archive the ASR-33 service manuals and other Terak docs.

This is something I've dealt with many times.
Generally I try to preserve any software and delete data. Right now to
give an idea, I aquired over 60 boxes of 8" disks with both. I will not
go into the several hundred 5" disks and handful hard disks.
I treat it as simply this, if I read it and it's not software I forget it.
I have other things to do mostly.

There's not much point in printing at a higher resolution than the scan.
I'm not familiar with the Umax 300P. Is that 300x600 intrinsic resolution, or
interpolated? You almost certainly want any interpolation or dithering turned
off, because it will de-sharpen the image.
There's also not much point in using grayscale unless you're scanning photos;
if the text is B/W, scan in B/W. It saves a lot of memory/filespace, and has a
better chance of losing the background clutter. That's why photographers copy
documents with very high contrast "line" film, which basically comes out black
and white with no shades in between.
You'll probably want to retouch the images to get best results (obliterate any
remaining clutter, and/or fill in any missing pixels), and you may need to
adjust the scanner's contrast or intensity setting(s) to get best results. The
optimum settings will probably vary slightly between documents.
Also, don't use JPEG compression, unless you're only compressing by relatively
small amounts. JPEG is a lossy compression system; the compressed-and-then-
expanded image is not the same as the original; detail *is* lost. GIF or TIFF
is better.
All this is a bit general, but is based on my own experience. Once upon a time
I was a photographer (for a printing business) and I use a small desk scanner
myself, for faxes and assorted images. More often than not, I end up either
retouching the images, or rescanning with different settings, and quite often
pass them through image enhancement software afterwards.

I've added a new page to my Weird Computing Machines site. The page shows
my two S100 machines. I invite you to visit, as these really are quite
fascinating computers - especially the first!!
http://www.comcen.com.au/~adavie/weird/
Please select "S100 bus" on the menu to view them.
Lots of software and documentation came with these machines - its a bit of a
dilemma... I'd love to get it all running again, but have neither time nor
space. They are destined to spend their time "looking pretty" for some time
to come.
Enjoy!

In Britain (and the rest of Europe) the Data Protection Act is supposed to
cover anything that could be considered "personal data", ie relating to a
person or persons, and data that can identify a person is particularly
protected.
Nonetheless, leaks occur.

A few years ago, I was given a big Fujitsu SMD drive and controller. I only
really wanted the drive, so I hooked it up to a different controller (different
format). I was very surprised to find it was not only readable, but full of a
certain very well known insurance company's head office records, including a
lot of stuff that I'm sure was commercially sensitive. I just reformatted the
drive.
I've since had exactly the situation you describe with three RZ23s. One had
VMS, the other two had an assortment of what looked like someone's office
files. I wanted two for a unix box, so I reformatted them fairly promptly
without even bothering to see what the files really were. I kept the VMS one
for a while in case it was useful, but when I finally got my MicroVax, it had
all the drive space I needed, so eventually the last one got wiped too.
I've had this happen so often that I've almost given up looking to see what's
on drives; it's hardly ever useful or interesting. I used to keep useful
software, but I wouldn't read personal files. Somehow theft (copyrighted
software) doesn't seem quite as morally objectionable as peeping.

I've got the DHV11 manual somewhere in this huge pile of ring binders on the
floor... If you have any specific questions I can look them up, but I seem to
remember it's fairly similar to a DH11.

Hmm. Guess that means I might owe you a doughnut. Did you try posting

I attended the first "Amiga wake" party when Amiga Corp. closed in
Los Gatos. They had one of those "black box" wirewrap Amigas there.
I will continue to deny that I had anything to do with
the rescue of the Amiga sign from the lawn of the old office. :-)

Hi from Rostock, Germany
My old DecStation 5000 / 200 got hardware -problems.
Having it repaired is rather expensive with digital in germany.
As I still have data on two rz 55 / rz 56 disks I am looking for a
DecStation 5000 / 240 or 5000 / 260 system 2ndhand,
with a sytem 2 user license of ultrix 4.3 or 4.4
I would need only the system box (with hard disk built in ) as my
Dec (well rather Sony) 19" monitor is still well and alive ...
Shipping from US / CAN via UPS or DHL ...
Willing to pay about $ 500 (depending on type of sys and size of hard
disk)

I recently got a "Baby Blue CPU Plus" card by Microlog Inc. It's a CP/M
Card for PC's, and has a 4.77mhz Z80B with 64K RAM (available to DOS too).
Also "accepts several popular CP/M 5.25-in soft-sectored disk formats".
It's a full-length 8-bit ISA card, and has no docs or software, but the
original box has the installation info (including limited dip-switch
settings) printed on the back.
Anyway, anyone have a manual or software I could get a copy of? Thanks in
advance!

I don't know much about Kaypros, but is it possible that one of the sets of
drives is 40-track and the other is 80-track? Or that one set is single-sided
and the other is double-sided? When you start up the machine and it tries to
boot, does a light come on, on the disk drive (which would indicate that the
drive is being accessed)?

Usually there's a set of jumpers, or sometimes a small DIL switch pack, which
select one of four disk addresses. They may be labelled DS0, DS1, DS2, DS3 or
perhaps D1, D2, D3, D4. D0=A and D1=B. You just need to switch the jumper
settings. Even if they're not labeled, you should find that all but one of the
jumpers (the drive select jumper) in one drive match the jumpers in the other
drive (of the ame pair).
If you open up the drive case and tell us what the make and model number of the
actual drive mechanism is, someone can probably tell you the jumper settings
and whether the drive is 40/80 or SS/DS.

I had these posted in late February and had to "cold shoulder" a few
people since there were some people that said they definitely wanted
them. Those same people have not contacted me in some time and I'm
posting these again as I need to get them out of my way soon or they
will get new homes in the landfill....
Have three older terminals, condition unknown but in good physical
shape.
Digital VT100, no keyboard
Digital VT220, no keyboard
Visual 102 with keyboard
I'm going to ask $5 for each plus shipping to more or less cover the
time involved in packing and running these to the shipper, but otherwise
they're here and awaiting some interested foster home to contact me
about them. Neither weighs a lot but due to the glass crt they aren't
featherwight either.
I also have for $10 each plus shipping three Hewlett Packard 700/44
terminals in great physical and electrical shape. They emulate quite a
few different things and come with like new keyboards as well and have
both a current loop and a 25 pin serial connection in the back.
If the people that said they wanted them are still reading the posts in
this area and still want them they need to contact me immediately. I'm
sure the Digitals are wanted irregardless of condition for parts or
collectability. The HP's are great dumb terminals for those of you
running minis and mainframes that otherwise have no human interface and
possibly even for automated data aquisition and test racks.
If I don't get a firm response by the middle of April (say tax deadline)
they go away for good. It's too much of a problem to have them in much
needed space here to mess with them. Those interested should let me know
what they want and their zip code to calculate shipping, either by UPS
or USPS. I can only take a money order or cashier's check for the amount
due and shipping, in advance of shipping.
COntact me directly. I'm in the process of finishing my new shop and
these are a definite nuisance to have to walk around since I personally
have no use for them

Rerun of what I posted earlier. I really need to find a home for this!
Sanders and Associates 101 Modem Tester
Smaller sized benchtop case (11x4x10 approx that sits on handle) with 25
pin sub-d male and female connectors (RS-232??) as well as individual
test points for each signal on back. Nixie 3 digit error display, over
run/count gate/sync lost lamps, test pattern/test length switch,
BPS/sync/self test switch, 1 error 10(3) bits button and start button on
the front. The unit was made by Sanders & Associates Inc, Digital Comm
Dept, Nashua, New Hamster. It appears to be of middle/late 80's vintage
and is probably a worthwhile instrument yet for telecomm or network use.
I can just imaine what something like this went for new.
Asking $35 plus shipping (10 lbs maybe) for the unit. I'd really like to
find someone that can use this as I've been considering pulling the guts
and using the case for a homebuilt freq. counter, which I really don't
want to do.
Contact me by direct email if interested as soon as possible.
