[Coco] Coco monitors 1084s-xx ?

[Kip Koon]

Hi Farna!
I like the monitor also!  I just bought an RS-232 cable and some 6-pin din
plugs to make my own cable.  I could not find a commodore 6-pin din to db9
cable so I'm going to make one and use a com port motherboard cable from an
old PC to make the connection to the Coco 3.  I can hardly wait to see the
Coco 3 RGB on the 1084!  So far I just use the Composite video input.  It
will be a nice setup indeed.  
Anybody have any more 1084 monitors they don't need?
Kip

Hi Bill!
My 1084S-P unfortunately does not have the DB9 RGB connector.  Instead it
has 2 round DIN connectors for RGB input.  One is labeled "TTL RGB" with
8-pins and the other is labeled "lin. RGB" with 6-pins and I have no clue
what the pin out is for either input.  I would like to use the RGB inputs.
Would anyone have any information on how to utilize these inputs?  Any help
is appreciated.  Thank you in advance.
Kip

======================

That's a great monitor! You need to use the "Lin. RGB" input for the CoCo3.
That's "Linear RGB" (analog). The other is used for a PC (CGA).
This site has pin-outs for a lot of different Commodore monitors, the 1084
series included:

I used a 1084S back in the day. Just match the CoCo pins to the Commodore
pins, no signal conversions needed. You will have to use the sound out on
the back of the CoCo to the monitor to use the built-in speakers. It's a
great monitor for the CoCo! You can have the composite inputs connected as
well and just hit the input button to play games that use artifact colors
and won't display well in RGB.
