Need a certain monitor cable for 1902A:( Please help:(
Jerry Yeager
hook to it with my C64? I have the Chroma/luma cable, but there is only
input for sound and color (standard RCA input). Also, there are two 6 or 8
pin or something...some kind of DIN jacks for other monitors, but where do
I get those? I checked ebay and I can't find anything but the standard
cable (Chroma/luma).... Please help:(

Jerry,
You have two ways you can go. The 1902A will accept separated Y/C
video (same as S-video) and audio from the C64 via the 6 pin DIN on the
monitor side and an 8 pin DIN (assuming your C64 is a later version) to
match the computer A/V output jack. That is the preferred method because it
produces a better picture than composite video. If you can't find such a
cable, the alternative is a two wire version with the computer A/V DIN (5
or 8 pin) on one end and two RCA male connectors on the other.. one for
composite video and the other for audio. By the way, the 8 pin DIN on the
monitor is for digital RGB input, as from a C128.
From your description, it sounds like you might have a three-wire
cable, so it doesn't work with that monitor. It was made to interface a
1702 or 1084. Perhaps you can swap with someone who has what you need. If
you want to make your own cables, check out "pinouts" on my site.

VIDEO signal (pin 4). Sometimes, cables label the VIDEO lead as CHROMA.
If you can only connect the LUMA (pin 1) and CHROMA (pin 6) to your
monitor's video RCA jack, then you should try combining the LUMA and
CHROMA signals with a Y combining cable. Y cables should be available
from RADIO SHACK as well as at garage sales and such. The Y cable that
you may need will have 2 RCA jacks for the cable plugs and one RCA plug
for the monitor. I once tried this with a C128 and a BMC 1702 clone
and much to my surprise, the RUBE GOLDBERG cable arrangment worked.

I have a cable with an 8 pin plug labeled "computer" and a 6 pin plug
labeled "monitor". I was saving it for when I would acquire a 1902A
for $5 at a garage sale but I could let it go for a small (?) charge.

Rube Goldberg? Perhaps it is but it does work. I have used a trusty Y
adapter to connect a C128 to the video in on a VCR. Also to a green screen
monitor. I will second your opinion. It does work! :-)

It's not hard to get them nor should you be paying a fortune for them! Go to
RADIO SHACK and ask for:
- Radio Shack 5 DIN RCA Cable: 15.2cm Shielded Y-adapter Five pin DIN plug to
four phono jacks
Product: Intertan 42-2394D
Video = Yellow (Video Out)
Audio = Black (Audio Out)
These are the colors (female ends) that worked for me, and should be the
standard unless the producer changes
something.
Then all you need is your standard RCA cable with male jacks on both ends and
you're all set.
1) When ON, don't plug anything.
First, remember NEVER EVER EVER to plug the RCA jacks to your TV/Monitor with
C64 or Monitor turned on
(I always have both off, then plug the rca jacks in, then turn all on and to see
if I get anything - if nothing comes
on turn all off and try a different color). Usually it's a good idea to label
the cables as video in, audio in so that
you don't have to go through this process.
2) Plugging RCA jacks while C64 or Monitor is on, may damage your C64 SID
(sound) or VIC (graphic) chips.
It's so important that it had to be listed as a separate point.

The cable you were using was meant for Plus/4! (that I'm certain of - since I
plugged a similar one and got the same result: black & white picture on 5
DIN... The other 5 DINs for C64 work fine with 1902 monitors)... It tested the
1902 with the cables I stock and C64 works like a charm...
hope this helps,

RCA y adapter and combined the chroma and luma signal into one and plugged
it right in to the composite video in and it works great!!! Thansk everyone
for the help:) Much appreciated!
