RangerG Posted September 4, 2013 Share Posted September 4, 2013 (edited) I'm sure the answer is on here somewhere, but I couldn't find it. Does the Expansion Module #1 for the Colecovision also work on the Adam (letting you play Atari 2600 cartridges via the Adam)? I assume it does because it has the port for it. Does it work well? Does it take advantage of the A/V of the Adam? Take care. Edited September 4, 2013 by RangerG Quote Link to comment Share on other sites More sharing options...
Pixelboy Posted September 4, 2013 Share Posted September 4, 2013 I had an ADAM when I was a kid, and I did use the Expansion Module #1 with it. I don't recall any particular problems using it on the ADAM. Quote Link to comment Share on other sites More sharing options...
Tempest Posted September 4, 2013 Share Posted September 4, 2013 The expansion module works with the ADAM, but IIRC it looks a little dorky connected to it. Does the Harmony cart work with the Expansion module? Maybe it's time to sell my CC2 and 7800 and get a Harmony cart to use with my Expansion #1 and ADAM? I never play the 7800 games anyway.

ed1475 Posted September 4, 2013 Share Posted September 4, 2013 The Expansion Module #1 works great on an Adam with RF output. If you're using a composite a/v cable the sound doesn't come through and the volume has to be turned way up to just barely here the sound. The Harmony cart also works great with an Exp Mod #1/Adam.

RangerG Posted September 4, 2013 Author Share Posted September 4, 2013 Tempest, that's what I am planning. I want to use the Harmony on the Adam . Quote Link to comment Share on other sites More sharing options...
RangerG Posted September 4, 2013 Author Share Posted September 4, 2013 Ugh, I knew there was an issue. I remember reading about it somewhere awhile back. It's the sound. I like the Adam with A/V, so this won't work well for me. Thanks for the answers! Quote Link to comment Share on other sites More sharing options...

If you're using a composite a/v cable the sound doesn't come through and the volume has to be turned way up to just barely here the sound. I wonder why that is? Is there a fix? What about if you're using the F18A for VGA? I wonder if the expansion works then? Quote Link to comment Share on other sites More sharing options...
NIAD Posted September 4, 2013 Share Posted September 4, 2013 What about if you're using the F18A for VGA? I wonder if the expansion works then? I think you may be the only one with the F18A installed in an ADAM. The EM #1 does look out of place when attached, but a custom spray paint job to match the ADAM could solve that visual dilemna.

retroillucid Posted September 4, 2013 Share Posted September 4, 2013 ....but a custom spray paint job to match the ADAM could solve that visual dilemna. Or a custom spray job to match the Exp.#1. 1 Quote Link to comment Share on other sites More sharing options...
Tempest Posted September 5, 2013 Share Posted September 5, 2013 I just tried it and no, it does not appear to work. I get no picture or sound. Then again, I'm not sure if that module works at all as I've never tested it before. It might also have been the game, I only have a Pink Panther cart which uses a special board. Although if something like the Harmony cart works then I imagine PP would as well. Quote Link to comment Share on other sites More sharing options...
NIAD Posted September 5, 2013 Share Posted September 5, 2013 (edited) Or a custom spray job to match the Exp.#1. Like this one? Although I think I would have left the front snap on bezel the original color of beige or possibly went with black as well instead of silver.

If you're using a composite a/v cable the sound doesn't come through and the volume has to be turned way up to just barely here the sound. The Harmony cart also works great with an Exp Mod #1/Adam. I suspect the ADAM designers forgot completely about the external sound for composite A/V cable. I've analyzed the ADAM schematics http://drushel.cwru.edu/schematics/gameboard_working.pdf and the composite A/V cable takes sound directly from SN76489, instead of the right point just after C100 (the RF audio-in), so external audio technically is almost isolated and sounds very low. There is an easy way to test it, soldering two wires (one at RF-audio in) and another at ground and then connect this cable plus a RCA plug to TV sound.

Tempest Posted September 25, 2013 Share Posted September 25, 2013 Ok I've been thinking more about this, and for some reason it's bugging the crap out of me. Does anyone else out there have an F18A in their Adam and can test the expansion #1 to see if you get video through the VGA port? If I can get this to work (with a sound fix I suppose) then I can ditch my 7800. One less system to have have out. Quote Link to comment Share on other sites More sharing options...

Not a possibility, because the expansion #1 travels directly to composite out and RF out. The F18A generates directly the VGA signal and cannot decode video for expansion #1.

RangerG Posted February 18, 2016 Author Share Posted February 18, 2016 Is there no fix for this? This is the issue: If you're using a composite a/v cable the sound doesn't come through and the volume has to be turned way up to just barely here the sound. The expansion module works well and looks really good running through the Adam. But, the sound is really low. There have been several threads on this, but no answer. In the recent discussion of the "special" Adams that play SGM games, several posts mentioned ways to better the sound, but is there any known method that someone with basic soldering / electronic skills could do? Thanks! Quote Link to comment Share on other sites More sharing options...
NIAD Posted February 18, 2016 Share Posted February 18, 2016 Coleco modded the CV Delta Board to supply sound for the Composite 7-pin DIN Port the wrong way and that is why the sound from the EM#1, Opcode SGM and Juice SGM will be very low and you will have to turn your TV volume way up to hear anything. Early CV modders also made this same mistake. The answer for the Stand-Alone Adam Memory Console is to tap into sound output at C88 (I think it's a cap at this location). Rey just performed this mod and hopefully can post some pics or further details. Quote Link to comment Share on other sites More sharing options...

RangerG Posted February 24, 2016 Author Share Posted February 24, 2016 Rey helped me and this worked perfectly. It fixes the audio issue with the expansion module, and I can get a SGM to work on my Adam now (in the future). 2600 games look really good through the monitor out on the Adam. The module is not expensive to get, it saves wires and a power supply, and it seems to me above composite and almost svideo in video quality. Thanks Rey! 1 Quote Link to comment Share on other sites More sharing options...

I don't ever speak this way! Between the lack of sleep for days and it being the first time making a video like this, I kept losing focus just trying to keep my eyes opened. Next time I'll be sure to be wide awake when doing one of these 2 Quote Link to comment Share on other sites More sharing options...
RangerG Posted February 24, 2016 Author Share Posted February 24, 2016 Your help was much appreciated and so easy to follow. Yes, my wire was a different color and I didn't cut the wire (I de-soldered it like you) because it barely reached. 1 Quote Link to comment Share on other sites More sharing options...
