Ok, I've finally gotten around to attempting to scan a lot of the classic
computer documentation that I have. However, I have run into a problem
perhaps some here could shed some light on...
Whenever I scan a page from a manual, the scanned image on the screen looks
horrible. However, when I print it out it is absolutely perfect. Yes, I've
tried zooming in on the image on screen, it is unreadable still. One more
twist is that if I send the image to my OCR software, it turns it into text
with almost perfect accuracy. My scan settings are Line Art at 300dpi.
My scanner is legal size, a scanport 2400 and the application software is
Uload Photoimpact SE. My printer is an HP deskjet 820cse, and the video card
in my system is a Diamond speedstar A50 w/8mb ram. Since the scanned
document looks bad even when still in the scanmodule driver (before getting
passed to the graphics application), I don't think photoimpact has anything
to do with it.
I wanted to put some of the scanned documents up on the web, but since they
look horrible on screen I'm not sure how to proceed. Of course, they can be
downloaded and printed and look great, but... I have downloaded old dec
documentation that looked fine onscreen and printed fine too.
Any suggestions? What am I doing wrong?

Hi,
This gives a new meaning to the term LOG IN.
Ok i'll add the :) just to be sure that nobody ask me how I can Log in into

By the way did you get the docking station with it?

Antique Electronic Supply is a good source for tubes, substitution books,
troubleshooting guides, speaker cloth, and even the little rubber feet on
the bottom of old amps.
Here's the web address:

If you (or anyone on this list) is interested in a tube tester, I have a
spare one that I'd be willing to sell (or trade sometihing for). Email me
privately if interested.

Hi. I recently acquired a 1950's vintage Gibson GA-30 guitar amp. Never
having owned a tube-based amp before, I'm clueless about the proper way to
use this amp without abusing it (and it sounds great, so I want it to last
a long time! :v) .
For example, should I allow the tubes to warm up for a few minutes before
playing, and are there any special precautions I should follow after
playing (i.e. do I need a cool-down period before powering down?). Any
advice would be much appreciated. A quick Web-
search didn't reveal much except prices on used equipment.
Thanks!
Mark.
Hi,
Just a few possibilities.
Some hard drives will cause the above message if the 0 track has been altered (written over) linux is well know for this and the only way I know to resolve this is to low level format the drive. A lot of 386 and early 486 Award BIOS machines have an option of hard drive utility. If you do you're all set. I chose a 3 for the interleave value.
Try and boot the computer from the floppy, then run fdisk to see if you can reset the hd.
Check to see if any of the jumpers are missing from the pcboard part of the drive. Try typing the drive manufacture and model in Alta-Vista and see if the specs come up. That usually works for me.
If you have no set-up disk..... try the following on boot to get to the setup up Menu.
1) Hit CTRL+ALT+S or
2) Hit CTRL+ESCP or
3) Hit DEL

Try setting the scanner on either grayscale or monochrome, 150-200dpi. This
is what I use when scanning any tyoe of documnentation. I have an Artec
4800dpi scanner.

Sorry about that. Wasn't paying much attention and rather assumed
that the advertiser had set the response address to itself. Glad I
also neglected to attach the images. (If you want to see them,
they're on my home page and no, I didn't create them).
OBclassic: anybody got a copy of TRS-edit (a vi clone) for the Radio
Shack Color Computer that they're not using? The current GNU
equivalents seem to crash my system during the compile, I think that
they're too big for a 512k OS-9 system, or else I've got a hardware
memory problem -- and the CoCo 3 memory kits are rather hard to find
these days.

Hi Russ ("alice"),
Well, once again I high bid on the thing -- this time it closed at $51.01 --
hey, if this keeps up, maybe after three more auctions, he'll give up and
let me (as high bidder) get it for $17.38... :-)
