chart45 Posted November 16, 2018 Share Posted November 16, 2018 here the sound chip enhancer for the adam computer.... it give you the missing sounds from the sgm game on the adam it use only ttl chip so nothing to program very easy to build... i only test on ntsc system so i dont know if it work on others region system.... here the gerber files enjoy AdamSoundChip.zip 4 Quote Link to comment Share on other sites More sharing options...
Pixelboy Posted November 16, 2018 Share Posted November 16, 2018 (edited) Hmmm... I'm not sure this is going to work for every SGM game. As far as I know, the ADAM doesn't let the programmer switch the lower 8K (used by the Coleco BIOS) into pure RAM like the real SGM does. So any SGM game that runs in "full 32K RAM" mode (such as Gauntlet) is probably not going to work with this device.

ten-four Posted November 16, 2018 Share Posted November 16, 2018 Is this for ADAM built in or is this for ADAM expansion. Just curious. Quote Link to comment Share on other sites More sharing options...

chart45 Posted November 17, 2018 Author Share Posted November 17, 2018 i know how to add the 8k ram as you can see in the short video... you can also see how many ic's it require to do it so if i add the 8k ram i should put the 24k too so it's a ttl sgm and my ass get kick out so i wont do it... is there other games that require the full 32k of ram?? i will try every game that i have to see if there is some that dont work on the adam with the ay only... 1 Quote Link to comment Share on other sites More sharing options...
chart45 Posted November 17, 2018 Author Share Posted November 17, 2018 ok i finally test all sgm game that i have on 2 standalone adam and they all work... the game i didnt test yet since i lent them to a friend are gradius and peinguin adventure from opcode.. i will go get them and see if they work... so maybe some game will not work in the future but for the previous release they seem to work perfectly... i dont think i will do more test on this.. you build it if you want... if you want to be sure 100% compatibilities get the new phoenix or a sgm... 1 Quote Link to comment Share on other sites More sharing options...

jltursan Posted May 27, 2022 Share Posted May 27, 2022 Thanks for sharing!. The PCB doesn't have any holes to use screws, does it fits firmly inside the case? Quote Link to comment Share on other sites More sharing options...

The card edge connector is pretty much a perfect fit as well as the rest of the pcb. Just use some doublesided foam tape on the underside of the pcb to hold it in place. 1 Quote Link to comment Share on other sites More sharing options...

rietveld Posted June 3, 2022 Share Posted June 3, 2022 I also noticed that this sound enhancer does not work properly when attached to the colecovision Adam expansion module 3. The Adam produces a echoing cannon sound that only goes away when the the SGM game is loaded and running. Any other instance other than the game produces this constant noise Quote Link to comment Share on other sites More sharing options...
