[Coco] Modern display options for CoCo2?

[Brendan Donahe]

Rich,

You have several options when it comes to your CoCo 2.

 At least some of my CRT and LCD TVs still support using analog channel 3
or 4.  When I want to display my CoCo 2 on one of those, I ditch the old
TV/game switchbox and use a direct connection between the CoCo and the
antenna input on the TV.  You can either use something like this (

with a male-to-male co-ax cable, or you can use (

with ideally a shielded make-to-male RCA cable.

Some composite adapters have been made available by Ed Snider which require
desoldering your RF modulator but produce really nice output.  I don't know
if he has any on-hand at the moment:

You could also use some online schematics to roll-your-own if you're so
inclined.

Lastly, depending on what type of CoCo 2 you have, I may have some CoCoVGA
adapters available.  (CoCoVGA is intended only for use in the CoCo 1 and 2,
because it plugs in where the 6847 video display generator chip is
connected.  It is incompatible with the CoCo 3's GIME.)  They are $95 plus
shipping.  You can email me at info at cocovga.com if you want to know more.

Thanks,
Brendan
