Before someone like Tony jumps down my throat, U and V are _amplitude_
modulated onto the subcarrier, in quadrature with one another. Thus the
phase of the subcarrier gives the hue, and its amplitude the saturation.
I hope you are not any more confused than before :-)

You have a great listserver here, and I'm glad I've subscribed. I'm going
to assume (and yes, I know the consequences <g>) that advertising a
special-interest listserve is o.k. provided it's within the realm of this
list.
Well, they are. I have started two listservers, one of which used to be
*very* popular in it's heyday (which, unforch, has passed it seems) and the
other solely because there wasn't one.
The first is a replacement for Andrew Diller's Model 100/102/200 listserve,
and one can subscribe by going to the web page at:
http://home.northernway.net/~zmerch/signupform.html
or sending an e-mail to m100-request(a)list.northernway.net with "subscribe"
(no quotes) in the _Subject:_ of the message. To send messages to the list,
e-mail m100(a)list.northernway.net.
The second is my own creation, because there was no Tandy Model 600
listserver. It can be accessed thru it's web page at:
http://home.northernway.net/~zmerch/signupm600.html
or sending an e-mail to m600-request(a)list.northernway.net with "subscribe"
(no quotes) in the _Subject:_ of the message. To send messages to the list,
e-mail m600(a)list.northernway.net.
I don't have to mention to anyone just how wonderful these lists can be for
information... If you're interested in these machines, come on in and join
the fun!
Thanks for the bandwidth,
Roger "Merch" Merchberger

I haven't received any new issues of the Classic Computer mailings since
June 7th. Is there anything wrong? This has happened before, maybe it's
my mail provider. Should I sign off and re-register as a new member of
the list?

I think that we should take this a little more seriously. I propose that we
form regional SWAT teams. In the event of a classic computer crisis the
nearest SWAT team would be dispatched. Ideally each team would be comprised
of individuals who each had a separate area of expertise, i.e. Apple II,
Coco, TI, etc. Rescued computers could then be placed in foster homes until
caring, loving permanent homes could be found. :-)

Here's one for the printer books. I had a printer for my atari 800 that we
order out of the DAK catalog. It used a little cartridge shaped like a
bullet with a contact on the end. The printer would fire a spark and
actually burn the dots onto the paper to make the characters. It was
relatively slow, but considering it had to make about 9 passes to form a row
of characters it did pretty well. I can still remember the burning smell
everytime you would print something out. It was really a neat little
printer, and I can't for the life of me figure out why we got rid of it. I
still have the driver disk for it, but the actual name of the thing escapes
me right now. Wait a minute, it was an Olivetti, but I can't remember the
model. The coolest part was turning the lights off when it was printing and
watching the sparks fly across the paper as it printed. That's a printer I
would like to have again.

The San Francisco Public Library has terminals (DEC VT220's?) in every
library. My girlfriend was impressed when I used Lynx to telnet to my
account to check mail one day... 8^)

Actually, it was an InkJet... I think I still have some of the ink
cartridges around somewhere. (I was paranoid that I might not be able to
find more when I ran out, so I bought a whole bunch.) The sparks were to
convince the ink to jump onto the page, I think.

It was indeed an Olivetti, but I too have forgotten the model.
>would like to have again.
Me too. I remember demoing mine for ABACUS, the Atari Bay Area Computer
Users Society. That thing is what made it possible for me to pass English
in college! (I loathe the physical act of writing, so I never did any work,
until I could type it up on my 600xl (and later, 800) and print it out.)
