Good day now that InfoAge is back open. We had a couple of families visit with
very bright children.

Nick L. visited, and Jeff B./Jeff J. both came by too. Jeff B. returned our PET
2001 after fixing it at Degnan's recent tech weekend. Then he and Jeff J. and I
cleared some space in our storage area.

Doesn't sound like much, but we had a full day.

pictures?  Colors?

I have something that I would like to show. It wasn't a movie, but a TV show
that lasted 10 episodes.  We don't have to watch all episodes, just a few.
Can I use that instead ?

Great ! I call dibs on "Fat Guy Stuck in Internet" It is 10 episodes lasting
about 12 minutes each. Totaling 2 hours.

*AND* it fits Bill Degnan's suggestion that it be technology related.

:-D

Hi,

Video can be either +ve or -ve depending on the system, I have no
knowledge of the Kaypro (is there a circuit somewhere ?), but the
following info from my basic video knowledge.

In a basic Black/white video signal (usually 1V p-p)  0% is the sync
pulse level, 33% is black, 100% is white. The Black level is usually
"clamped" in some way and the sync pulses both line and field are
imposed on on black as a pulse to 0%, the actual video is then left to
fill the remainder between 33% to 100%.

It would appear that your 100% "white" level is ok, but that the 33%
"black" level is changing so the flyback is seen on screen. Some systems
generate a "flyback blanking" signal from the video to turn the CRT beam
off during this period, if the Kaypro does it may have failed. Others
rely on the video to block the beam during flyback purely by the video
being below the 33% level.

As The Kaypro seems to get worse with time I suspect a component/s in
the video chain is drifting so that the 33% level drifts towards the
100% level, it could be either in the video generation or the display.

The basic structure of the video signal is good as the text is displayed
in the correct place and time, so the sync signals are correctly placed,
just that the "black" background level appears to drift up from black.

Basic video structure here - http://www.ni.com/white-paper/3020/en -
there are many examples on the web.

A circuit of the Kaypro video system would help, anybody ?.

Regards,
Mike

They very, very, VERY much look like red LED's to me, maybe shorter in height
than some. If you measure the dimensions of yours, I can check my junk box to
see if I have some of similar dimensions. Others of course can do likewise.

   I am almost positive that I have a pile of these.  I will go take some
pics and send them to you for positive identification.

    How do these look for a match?  They seem to match the description
you gave in your other email.

    http://www.neurotica.com/misc/leds-1.jpg

    I have other rare LEDs if these don't match. (I have a bit of an LED
fetish)

    Sounds good.  I have a bunch of others that we can go through until
we find the right one.

    Neat!  I love LEDs in general, but I especially like metal-encased
LEDs.  I have some nice old Russian ones, red and green, that look very
much like TO-18 packages but aren't quite the same size.  They look
great.  I'm looking for the "right" project for a bunch of those.

What's a fair price for a Microsolutions Compaticard I, with box,
manual and software diskette?  Someone is interested in mine.


Mike Loewen 		 mloewen@...
Old Technology       http://sturgeon.css.psu.edu/~mloewen/Oldtech/

Mostly duplicated TRS-80, early apple, macintosh and PC (386 and earlier) stuff.

I just have too much to work with. No reasonable offer refused. Come and load
you car. All stuff located in Wantage, NJ. I WILL NOT SHIP.

Replies and questions off list please.

Some items I'm parting with:
GBC System (rebadged northstar advantage)
TRS-80 model III
TRS-80 Model III motherboard
Apple II
Apple IIgs
Mac SE (2 I think).
Several XT and 286 clones.
9-track overland data drive with controlling PC.
Non functioning TRS-80 model 2000's
3.5" disk drives (OT for this group, but I have a box full of them)
CD Drives (panasonic and IDE interface)
IDE hard drives (240 meg to 10 gig)
Commodore 128 unknown condition
IBM PS2/50

Any interest?

You don't say where you are.  OS/2 software from the 1.x days has really
gotten pricey.  I have stopped buying stuff on eBay since I won't pay
$100's for stuff that is just to sit on a shelf.  We used to give a lot of
this old stuff away at Warpstock events in the US and Europe, but the
sources have dried up.   Have you tried local computer clubs for anyone
that has this stuff they are looking to get rid off?

What's that blue underline mean?

I may be interested in some.  How many do you have?

   These are dynamic RAMs by the way, unless my own RAM is experiencing serious

I'm sure you all will be bitterly disappointed to hear that
the updates have been postponed till January 2013.
Yes, I clicked through their awful link to their "blog".

I'll be interested in hearing if you guys think their claim of oldest is true.
I did enjoy the video, love seeing old pixie tubes in action.
It would be really cool to do a video tour around the machine
what's in it, any interesting/unusual theory of op, etc.
Ditto goes for other old machines.
Maybe such presentations are available on DVD from somewhere?

>> I'll be interested in hearing if you guys think their claim of oldest is

It's the oldest digital large-scale computer. But there are probably some people
with Simon computers from the 1950s. Those are digital, just not large-scale.
