[Coladam] Coladam Digest, Vol 86, Issue 5

The enchanced video board is the F18A, available here:
 
http://codehackcreate.com/archives/30
 
It offers all of the original modes but outputs them (by pixel doubling) to 800x600 resolution.  It also offers some new video resolutions and an 80 column text mode.  And he had some extra space in there so he added a video memory based graphics processor (in assembler the same as the TI 99) so that it can do tricks purely in video memory.
 
It has a backwards compatible mode, and then it can open up new features if you enable them.
 
I think that for 3D you'd need at least a 60 fps interlaced video mode, with flicker graphics and maybe a plasma TV.  So 256x192 wouldn't work for that, but 512x384 (which is supported on the 9938 and 9958 video chips) would do the trick for 3D.  Something new to potentially experiment with in the future I guess.

Overkill as the ADAM is still only outputting, at best, a Composite Video 
signal. The video or resolution won't be any better unless some major 
upgrades are made to the ADAM's video chip, etc. and really how far can you 
take it seeing as any replacement Video Chip has to stay be compatible with 
the CV&ADAMs current one. Well that's an easy answer...

There is such a video upgrade board for the ColecoVision and ADAM that was 
announced last year and made by a member on AtariAge that outputs a VGA 
signal. For the unskilled, it's a major upgrade and they would have to find 
someone to perform the modification for them. I can't recall the name of the 
product, but you can search on AtariAge for the CV, ADAM, TI-99/4A video 
upgrade board. Last I heard, the developer has a large number of pre-orders, 
but there has been an extended delay in the production of the upgrade 
boards.

However, the resolution is still only 320x240 unless somehow this board can 
upscale to higher resolutions. I'm going to have to reread thru that thread 
once I find it.

For what it's worth, Composite Output thru the use of a Commodore Monitor 
Cable to a Sony 26" LCD's Composite Video Inputs gives me a tremendous 
picture that is even better than some of the best Composite Monitors that I 
used back in the day especially since it's so much larger.

Anyway, why stop at HDMI... why not go crazy and ask for 3-D as well.

What we need is a HDMI output on the Adam. All modern computer monitors and 
TV’s being manufactured have a HDMI input. That would be a major upgrade to 
the ADAM. For those that have a Colecovision with expansion module #3 there 
are some that are using a 480i component video output modification which 
produces the best picture quality every seen on the Colecovison/ADAM.
