connecting c64 to 1084-Monitor
Raymond Carlsen
>
You will need a cable with a 8 pin DIN (plugs into the C-64) on one end
and three RCA plugs on the other. The three RCA jacks on the monitor are
color coded: Yellow is for Luminance (black & white information), Red is
Chroma (color information), and White is Audio. For use with a C-64 with
that hookup, the switch on the rear of the monitor labeled: CVBS/LCA
should be in the LCA position (Luminance+chroma+audio). CVBS stands for
Color video with blanking and sync... in other words NTSC video.
The 1084, like the 1902 will also accept RGBI from the 128, and analog RGB
from the Amiga. The 8 pin DIN is for TTL (RGBI) and the 6pin DIN is for
analog.

does anybody know how to connect the C64 to the Commodore 1084-Monitor?

Vic-20's and old C64's have a 5-pin rather than 8-pin DIN for the
video output, and the luma is actually a full CVBS output. Still
works if you plug it in as described above, though.

I memory serves there are assorted inputs on the back of that 1804
One of them is either a DIN plug (I don't think so) or three RCA type jacks
(Another is 2 RCA type jacks, also called PHONO plugs)
It is the 3 jack version that the 64 connects to. Just like a 1702 and using
the same cable. However if the seperated video input is a DIN plug socket
then you will need the proper cable.
Redmond cables in Redmond, Ca. (If they are still in business) should be able
to make such a cable for a fee, They made a number of special cables for the
128 so I'm sure they know how to make standard ones.

When I bought my 1084, a c64 cable was included!

I personally just used the stereo cable which ordinarily connects my 18
cm reel tape deck to my amplifier: 5 pins DIN on one end, 4 "tulip" (=
RCA?) style plugs on the other. The holes in the 64 that aren't in the
plug are fortunately not needed.
To determine which color tulip plug should go into which 1084 connector
(actually, I have a 1081 but afaik they are identical), I used simple
trial and error. One should go into composite, the other into audio.

This sounds fine and probably I could have figured it out myself :-)
But unfortunately the 1084 in question doesn't have the three color-coded RCA
jacks :-(. Is this a difference between german and US versions of that monitor?
It has only two jacks labeled CVBS and audio. I suppose I can't just connect
Luminance and chrominance to the CVBS. I think I remember the c64 having a
CVBS output but I can't find out which plug and which pin.
Any more suggestions?

My C64 has an 8 pin DIN and it produces CVBS (composite video). At least
the monitor does show color :)

image on newer C64's or 128's; old C64's have full composite on the
luma output -- the 5 pin DIN on the 64 is the cue for this) to the
monitor's video in (CVBS).
You can also mix the chroma and luma inputs with a "Y" adapter but you
lose picture quality.
The best thing to do is to find a non-Commodore cable (I bought
several at a computer surplus store a while back, but no I won't get
rid of them) that has the right signals or to make your own.
The pinout of the DIN is in the user manual for the Commodore.

) CVBS is not the only form of composite video. There is also "separated
) composite," or LCA. Phil Pugliese meant that the pin documented as "chroma"
) does not also carry a "luma" signal. All of us agree that every 64 produces
) both CVBS and separated composite.
On the 5-pin DIN 64's, the video connector has:
pin 1 Luma
pin 2 Ground
pin 3 Audio out
pin 4 CVBS
pin 5 Audio in
On the 8-pin 64's, it has:
pin 1 Luma
pin 2 Ground
pin 3 Audio out
pin 4 CVBS
pin 5 Audio in
pin 6 Chroma
pin 7 N/C
pin 8 +5V
The cables with 5-pin connectors put CVBS on the "chroma" pin, and
there is no separated video signal on those 64's! The separate luma
output makes the picture clearer but is not necessary.

Right, but if you don't have the right cable for CVBS but you do have
a "Y" adapter, you can use it to get color. It is especially good for
a temporary hookup to a CVBS monitor.
