I think the machine you are thinking of might be the N* Dimension. The Advantage
still uses 10-sector floppies.
I've never seen the Dimension but vintagemicros on Ebay was selling one a while
back and had a picture of it. Apparently it was MS-DOS compatible.
Does anyone have a CMD CQD-200/TM or CQD-200/M and an EPROM programmer
or other means of reading the EPROM images that could send me a copy?
I think I have mostly figured out the CSR decode PAL for a CQD-200/T
and programmed a new one and now it responds to both the disk and tape
CSRs, but only the tape CSR looks like it has normal values. Maybe I
also need to replace the EPROMs with CQD-200/TM or CQD-200/M EPROM
images to get it to respond normally to the disk CSR.
I have had encouraging results so far doing the same to convert a
CQD-220/M into a CQD-220/TM and got it working with both a disk and a
tape at the same time.

I sent the DEC ROM info to the VT220 Font author, and he responded with
thanks and also wanted to know if anyone had PDP-11 CPU tests.
I noted he might want to join here, but I thought I'd start the ball
rolling on his request.

*Many thanks,
I found a leaking capacitor just as you have described. I've ordered
new ones and will soon be able to replace it.
I'll let you know if that fixes the problem (It should!).**

This issue came up a few months back. Apparently gmail filters the

Perhaps somebody else can rememebr the details.

old DEC neons tend to flicker randomly (and it's truely random).
The basic design is for the mains :
Mains in--->filter --->Breaker-+--->Unswitched outs
|
+--->Contactor (big relay)-> Switched outs
The contactor is controlled (in the 861) by a reed relay on the little
PCB inside. This has a differentially-wound coil to give the 'ground for
on' and 'ground for off' functionality on the 3 pin connector. The reed
relay coil is powered by a little transformer/rectifier/capacitor
circuit, mostly on the PCB.
My first suspicioun is that capacitor. Open it up and look for any
electrolytics on the PCB inside.

Hi guys,
I'm after a program that can convert TIFF files into PDFs. I've seen
Eric Smith's "Tumble" app, which works great... but only for B&W TIFFs.
While I can use Imagemagick to convert the images to B&W, that defeats
the point: there are photos on the scanned pages, and I'd rather like to
keep them as photos, not black splodges.
Also, has anyone come up with a "best practice guide" for manual
scanning? At the moment I'm scanning like this:
B&W text only: 600dpi, black and white, threshold=50%.
Text + photos: 600dpi, greyscale, then despeckle and scale down to
300dpi.
Obviously if there are better ways (in terms of quality and/or speed)
I'd like to know before I scan a ton of testgear manuals...
Also, does anyone know of an app that can take the PDF file, OCR it and
then insert the text as a background layer while leaving the image
alone? I'm pretty sure Acrobat can do this, but like most Adobe
software, the price tag is somewhat... eye-watering. "If you have to ask
how much it costs, you can't afford it."
Thanks,

I'm pleased to announce that the maintainer of Linux cwtool has
implemented working support for reading and writing Intel M2FM "DD"
diskettes as used with the Intellec development systems :-).
Karsten did some analysis of raw bit images I sent him and produced a
working driver within a week! As a "smoke" test (my MDS800 is not
functional at the moment), I duplicated the ISIS-II system diskette and
sent the copy to a person with a working system. It boots, catalogs and
otherwise looks fine.
I have about 20-25 original distribution diskettes for the MDS800 and will
get busy imaging them ASAP. Who would be willing to host these?
They are "cooked" images, so it would be possible to extract the files
>from them with a bit of work. However, they're obviously of the most use
to folks with access to a Catweasel board (and an Intellec system).

Hi,
are here people with intimate knowledge of Honeywell Level-6 (Series 60) computers? Or documentation?
I got two Level-6/06 machines. Those seem to be somewhat different from the rest of the line as they
should be downwards compatible to the X16 machines. But I have no single manual for them. All I have
are some Level-6 manuals talking about other machines. In one of them, the 6/06 is mentioned as
special and "Series 700" (WHAT is that?!?) compatible. And that it is explicitly not subject of the
manual and that it as its own manual that I do not have. I also don't have any schematics.
Best wishes,
Philipp :-)

First the TU56 broke, then the Lilith disks goes, and now it is the HP Integral's turn .
The Integral, stored a year ago in working condition, has a display problem.
After switching on the Integral makes all the right noises, but the display remains off.
Anyone has a pinout, or schematic , of the Sharp LJ512U03 EL-display as used in the Integral ?
( there is something, but not much, in the 1985 HP Journal )
a replacement will be hard to find, and far too expensive of course.
I do wonder how those with 100+ computers keep them all runnning, I have maybe 25 classics and find it hard to keep them alive.

There was some recent interest in Adam Osborne books.
I have found one each of the following:
"An Introduction to Microcomputers Volume II: Some Real Products, June
1977 Revision"
"6800 Programming for Logic Design"
Make me an offer.
Shipping will be USPS Media Mail from zip 65775.
thanks
