Zenimus Posted November 3, 2013 Share Posted November 3, 2013 Here's a short video that shows it a little better. trim.943663FE-AD47-474E-9609-49A8334E1A28.MOV Quote Link to comment Share on other sites More sharing options...
QuarkStar Posted January 1, 2014 Share Posted January 1, 2014 I'm having trouble getting the colors quite right with this mod: If I get the whites looking good then the yellows are a completely washed out tan-brown; conversely, if I get the yellows looking nice by turning up the blue-difference potentiometer, then the whites invariably end up in some range of yellow to green. I have yet to find a decent compromise. Note: I had to get the blue potentiometer up fairly high to get most of the colors to pop, but I can't really increase it further without turning the blacks into a bright blue; they're already a little bluer than they should be but still look alright. I tried several times following Harvey's guide on adjusting the colors, but no luck. Any recommendations on how to fix this? Quote Link to comment Share on other sites More sharing options...
Yoyodude1124 Posted July 6, 2014 Share Posted July 6, 2014 (edited) Are you still making boards? I just recently acquired my Coleco, and would really like Component video. Edited July 6, 2014 by Yoyodude1124 Quote Link to comment Share on other sites More sharing options...
Tighe Posted August 7, 2014 Share Posted August 7, 2014 I am really late to the party on this thread, I would love one of these if you are doing a second batch. Quote Link to comment Share on other sites More sharing options...
Van Slanzar de Fanel Posted September 21, 2014 Share Posted September 21, 2014 I wish I knew about this before. A Colecovision is one of the consoles lacking from my collection, and getting better than composite (the only mod I can seem to find readily now) would be wonderful. I joined this site just for this.

Lios Posted May 9, 2015 Share Posted May 9, 2015 Color me very interested in this as well, I've long been meaning to add a component mod to my Coleco and this pre-made board looks perfect. Quote Link to comment Share on other sites More sharing options...
mightywiz Posted May 9, 2015 Share Posted May 9, 2015 yurkie here in the forums is offering a RGB mod and you have to buy an upscaler to use with it. Quote Link to comment Share on other sites More sharing options...
Lios Posted May 18, 2015 Share Posted May 18, 2015 (edited) I've seen Yurkie's mod, but I'd like something that doesn't require an upscaler (especially a specific one) and keeps as close to what's output natively by the VDP as possible. If I wanted it converted to RGB, I already have my own external solutions for that. Also, Yurkie doesn't appear to offer a DIY kit, which is exactly what I want.

Lios Posted May 18, 2015 Share Posted May 18, 2015 I've thought about the f18a, but being VGA kills it for me. Quote Link to comment Share on other sites More sharing options...
ApolloBoy Posted May 23, 2015 Share Posted May 23, 2015 Also, Yurkie doesn't appear to offer a DIY kit, which is exactly what I want.I'd love a DIY kit for RGB as well, it's very frustrating that he doesn't offer one for RGB but yet has one for composite video. I'm still leaning towards getting an F18a but I'd absolutely love to have RGB. Quote Link to comment Share on other sites More sharing options...
panzeroceania Posted July 15, 2018 Share Posted July 15, 2018 is this the only mod (other than composite video mods) tapping a video signal directly from the original hardware vs other mods that introduce a new video encoder chip? Quote Link to comment Share on other sites More sharing options...

Taijigamer Posted July 16, 2018 Share Posted July 16, 2018 Yurkie and citruspsi3000 mods both take Y, R-Y, B-Y signals directly from the VDP and convert them into RGBS using timing pots, op-amps and discretes. The designs are based on this application note http://spatula-city.org/~im14u2c/vdp-99xx/e3/SPPA004A_9928-29_9118-28_Interface_to_Monitors.pdf There isn't a complete IC based mod available yet. Check out citruspsi3000 RGB mod, comes as a diy kit, easy to install and it's better supported. 1 Quote Link to comment Share on other sites More sharing options...
HDTV1080P Posted July 16, 2018 Share Posted July 16, 2018 (edited) I would rather have HDMI for the ColecoVision/ADAM, however component video is my second choice. When and if a automatic IC based mod becomes available that would be the way to go. No pot adjustments would make the component video kit easier to install plus more accurate color quality when the IC is using native reference settings.

mobiusstriptech Posted July 21, 2018 Share Posted July 21, 2018 The citrus3000psi board is going to be your best bet for RGB. If you would rather have a pure digital HDMI out then the new F18 mk2 is going to be your winner. However that is not yet available. One of the tricky parts about these mods is that the signal attenuation varies greatly from one console to another. I've installed quite a few and found that no 2 have been alike yet. 2 Quote Link to comment Share on other sites More sharing options...

Wow - I was totally oblivious to the fact that an F18A MK2 was in development. Have now subscribed to the relevant AA thread and am on the waitlist. Thanks for the info.

HDTV1080P Posted July 22, 2018 Share Posted July 22, 2018 (edited) Back in the early 1990’s Micro Innovations was going to develop an external 80 column color video output for the Coleco ADAM computer that would have most likely have plugged into the side expansion module interface (Might have also worked on the ColecoVision front expansion module interface also). Of course Micro Innovations around the mid 1990’s stopped making hardware for the Coleco ADAM and never officially released the color 80 column video upgrade plug in adapter for the ADAM computer. However, my point is 100% of all hardware that Micro innovations made for the Coleco ADAM did not require any internal hardware modifications. Their products connected by ADAMNet, and the 3 internal expansion ports (not sure if they used the side ADAM expansion port at all but other companies like EVE Electronics and Coleco did). My point is none of Micro innovations products required one to take the computer apart and solder components onto the main motherboard. I do not have the schematics in front of me, but it should be possible in theory to develop a external HDMI output for both the ColecoVision and ADAM computer that would plug into the ColecoVision and ADAM expansion port. It would be powered by the console power supply. The HDMI adapter would have its own HDMI graphics card interface that would take the digital binary signals from the CPU directly and covert it to a native 480i 4:3 HDMI output. Basically it would disable the existing video display processor in the ColecoVision/ADAM and have its own video display processor with HDMI output. It would be really neat to have a OPCODE SGM that has a HDMI jack on the side that would output native HDMI signals.

One of the tricky parts about these mods is that the signal attenuation varies greatly from one console to another. I've installed quite a few and found that no 2 have been alike yet. If no front expansion module interface is made to upgrade the CoelcoVision/ADAM video quality, then I might one day take my ColecoVision/ADAM apart and solder a HDMI output video upgrade on it. I am guessing that the F18 mk2 when released well support the Coleco ADAM computer system and ColecoVision for HDMI output.

chart45 Posted July 22, 2018 Share Posted July 22, 2018 it's possible to run the f18a from the exp port of the colecovision.. not sure about the adam stand alone 1 Quote Link to comment Share on other sites More sharing options...
HDTV1080P Posted July 22, 2018 Share Posted July 22, 2018 (edited) it's possible to run the f18a from the exp port of the colecovision.. not sure about the adam stand alone Then if the F18 mk2 with native HDMI output can be ran from the ColecoVision and ADAM external expansion port, that would be the ideal way to go. Maybe someone could modify the SGM so that it contains a F18 with a HDMI port on the right side of the case (Maybe OPCODE games could sale new Super Game Modules with a built in HDMI port). The other solution is to develop an expansion module for the ColecoVision and ADAM that had the F18 with a HDMI output (An on/off switch would allow one to toggle between HDMI and the native VDP in the console). However, the HDMI expansion module would also need a expansion slot to plug in the SGM and other modules. ColecoVision/ADAM owners would spend up to $200 for such a product that offered HDMI output with no modification needed. Possible 200-300 F18 mk2 could be sold if it worked in such away. If the demand existed, a company could get a high-end Chinese computer graphics card company to make a dedicated HDMI video graphics expansion module for the ColecoVision/ADAM. The graphics card company would most likely want a minimum run of 500 and the research and development costs would be much more than designing a new power supply for the ColecoVision/ADAM.

Bmack36 Posted July 22, 2018 Share Posted July 22, 2018 A colecovision with F18a HDMI output will be out soon that will hopefully be in the same price range mentioned above Quote Link to comment Share on other sites More sharing options...

I hope you enjoy your design, its your decision if you do not want to mass produce this product. Its a lot of work and money to bring new hardware to the ColecoVision/ADAM community.
