Prime Minister Kaare Willoch, takes office in Norway.
* The 19th summit conference of the Organization of African Unity 
(OAU) convenes in Addis Ababa, Ethiopia.

Two RCA Laboratories Scientists Receive IEEE Award for Contributions 
to Video Disc System

The Institute of Electrical and Electronics Engineers (IEEE) today 
presented its 1983 Vladimir K. Zworykin Award to Dr. Jon K. Clemens 
and Eugene O. Keizer, both of RCA Laboratories, Princeton, N.J., for 
"outstanding contributions to the development of an electronic disc 
system for recorded television programs."

The Award was given to Dr. Clemens and Mr. Keizer at the 
International Conference on Consumer Electronics in Des Plaines, 

Dr. Clemens and Mr. Keizer played key roles in the development of the 
capacitance electronic disc system (CED). Both men were involved with 
the project since its inception at RCA Laboratories in 1965. The 
system utilizes a diamond stylus to sense video and audio information 
stored in the grooves of a specially formulated plastic disc. It is 
reliable, easy to use and relatively inexpensive. The system was 
commercially introduced by RCA in the United States in 1981 and will 
make its debut in the United Kingdom this fall.

In 1980 Dr. Clemens and Mr. Keizer were the only two Americans among 
seven scientists honored by the Eduard Rhein Foundation of West 
Germany for video disc developments.

Dr. Clemens, a native of Lansdale, Pa., received a B.A. degree in 
Physics in 1960 from Goshen College, an M.S. degree in 1963 and a 
Ph.D. degree in 1965, both in Electrical Engineering, from M.I.T.

He joined RCA Laboratories in 1965 to work on high density video 
recording for consumer use. During the years 1965 through 1970 he 
worked on various approaches to video disc systems including the 
capacitance pick-up video disc system. Since then his work has 
included all aspects of system development, including disc format and 
signal encoding systems and the responsibility for specifying the RCA 
VideoDisc standards.

In 1975 Dr. Clemens was named Head, Signal Systems Research, with the 
primary responsibility for developing the VideoDisc signal system for 
both mastering and player design, and in 1981 he was promoted to 
Director, VideoDisc Systems Research Laboratory. He was appointed 
Staff Vice President, Consumer Electronics Research, in 1983. Dr. 
Clemens has received three RCA Laboratories Outstanding Achievement 
Awards and the David Sarnoff Award for Outstanding Technical 
Achievement for his work on the capacitance electronic disc videodisc 

Dr. Clemens and his wife have three children and live in Skillman, N. J.

Mr. Keizer, a native of LeMars, Iowa, received a B.S. degree in 
Electrical Engineering from Iowa State University in 1940 and joined 
RCA after graduation.

Since 1940 Mr. Keizer has contributed to research in several areas, 
principally radar, color television receivers, color television 
display systems, and prerecorded video disc systems. He led the RCA 
video disc research team during its early years, 1964-1971, and 
continued to be responsible for research teams in video disc 
mastering and signal retrieval areas until 1979, when he became 
associated with RCA "SelectaVision" VideoDisc Operations in 
Indianapolis. He returned to RCA Laboratories in 1980, where he is 
now Staff Scientist in video disc research. Mr. Keizer has received 
two RCA Laboratories Outstanding Achievement Awards as well as two 
David Sarnoff Awards for Outstanding Technical Achievement.

Mr. Keizer and his wife, who have two sons, live in Princeton, N. J.

I would guess this could be a malfunctioning IC602 or IC603 chip, but 
it could be a chroma level adjustment issue as well. To adjust this 
during playback, remove the cover from the player, load a disc, and 
with the disc playing, lift the signal processing board up to the 
vertical service position. Note that playback will not occur if you 
lift the board prior to the start of playback, unless you defeat the 
photo-interrupter mechanism.

While watching the displayed image, note the position of R419 and 
then carefully rotate this adjustable resistor left and right to see 
if the color returns. If this doesn't work, return R419 to its 
original position. At this point, circuit analysis will be necessary 
to diagnose the problem further.

For collectors in the United States, note that it is normal behavior 
for a PAL player like the GEC McMichael V5000H to display Black & 
White video when attached directly to an NTSC television. This is 
because the PAL luminance signal is close enough to be displayed in a 
slightly truncated fashion, but the PAL chrominance signal is off at 
an entirely different frequency. To display color with such a setup, 
a PAL-NTSC converter is needed:

Subject: CED Central
From: James Curiel <jacuriel>

Dear Tom and CED Community,

I have been confronted by the realities of having a new baby and also 
increased demands for my time at work, and I have come to the 
conclusion that I no longer have the required time to run CED Central.

My wife and I started CED Central originally in March 2002 as a 
service to the CED Community in a time when shops were closing and 
Thompsons was shutting down their CED parts division.  The web page was a formalization of an impromptu repair service 
I had been doing for people here in Northern California through an 
informal network.

The web page has taken on a life of it's own, and I have enjoyed 
meeting people around the country and in Canada.

But now it is time to pass the torch onto someone else who loves 
working on these machines and helping people to keep the players 

I am selling CED Central, that is the web page, and our inventory. 
Currently, our inventory includes:

136 stylus cartridges (models 149000's, 154100's, 154216's)
107 RCA videodisc players
28 Toshiba players
6    Realistic players
28 in the box never used SKT-100 players
7,000 used discs approximately
2000 never used discs, still in wrappers approximately
1 KAB EV-1  Record Cleaner
12 New In the box Digital Command Remotes
A few New in the box parts for players, and some RCA Televisions
Shelving for approximately 5,000 discs and 30 players

Those of you who have patronized CED Central know that I try to keep 
the costs down, don't like haggling, and like simple, nice round 
figures.  Thus, I am selling the website and the inventory for 

Ideally, the person purchasing CED Central  will know how to work on 
RCA videodisc players.  They can run the website and service out of 
their home.  It will take 30-40 hours a week to service 1-3 players a 
week, and also sell 1-3 players a week, and sell approximately 10-20 
discs a week and 4 stylus.  If you have the time and inclination you 
could increase the volume being sold.  My problem for about 8 months 
has been trying to slow down the volume because I did not have the 
time to keep up with the demand.

I will put you in touch with our supplier.  Currently, we have an 
exclusive arrangement with our supplier for stylus and New remotes. 
This will need to be renegotiated.

Please, only contact me if you have the time and the enthusiasm to 
work on these players.  The $15,000 price is more than fair, and is 
not open to haggling.  I just want to recoup some of my investment 
and not lose too much.

The disc inventories are ballpark figures, could be more, could be 
less, most likely more.

The players are a double edged sword.  No one will steal them because 
they do not work and very few people know how to get these players to 
run properly.  That's one of the beautiful things about these 
players.  Your labor and knowledge makes them valuable, and makes 
them work.  Even the new in the box SKT-100 players, you will have to 
service, test, and repack.

I have enjoyed helping people with their players.  I have found the 
people that have CED players to be very honest, honorable people that 
have lots of character.  People from media executives, people who are 
researchers, and noteworthy developers of the format and television 
itself, and also hardworking people like truck mechanics, waitresses, 
and so forth.
