i hope to be contacted by eduardo to get one but with all i read i think i will wait for a long time hope that i will be able to find a way to play all the game until i get my sgm....

ok tight some connection on the breadboard and now work perfectly thank to all of you http://i288.photobucket.com/albums/ll183/chart45/F65F3028-3E0B-44D8-95C2-1F05DE17EE99-16416-000009021204C964_zpsff3d1ae4.mp4 now ill try to do something clean

for sure I'll use a board and solder everything this was just to know if it was possible to do it now I will work on a pcb for the chip is there something else I should know before doing it like the capacitors and juste another thing when I remove y2 or y3 don't remember your software detect the sgm module so is it possible to play game design for the sgm without the sound chip

ok here's the result of the ram test failure in the lower 8k this is the y3 i think should i AND it alone and leave y2 and y1 together

ok tomorow ill get the capacitor... but when im using only 1 62256 the game load but is slow and lot of glitch.. when i put 2 62256 and using 2 i/0 for one of the z80 game running perfec until i die then problem start. just tu be sure should i use only the 62256 or i should use something else and again im not electronic dude i do what you guys telling me and what i find on google so if i need something else tell me and i know i need a sgm but i cant get one thanks again to you guys and all of you who try to help me in that project

ok now using 2 62256 ram game load play nice but thant crash or sound bug probably because the breadbord but if someone have an idea ??? i ordered a 64k chip to replace the 32k should do hope so 5-11 can i have your opignion please

game load but it's slow i dont know if its beacause im on a breadboard or its the chip do you have a idea??? and i have to put the oe to rd beacause when i put it to the ground that mess the graphic and again thanks for your advice you re the men

receive this in the mail today hope that will work

i alredy order a 62256 should arrive in the next few days but found this one should i order it cause this one have 18 address as6c4008 thanks for your help and count me for your pcb

ok so i should wait to get a 62256 chip before make other change. what is the best option for the chip i will order one

I think I miss the first part to put a10 to a14 to the rest of the coleco how ??? I cant figure

for now it's a no go the game load but still get the msg that i need a 8k ram i think ill need help cause in then first post you tell me that i need to hook a0 to a15 but i cant on a 6264 chip do i have to use something else

thank you I will give a try this week and post result

ok im really not sure about this parts since i dont know if i need to add a ground if this drawing is not good could you draw one for me as a example or write some additional info cause I read and read the wiki link but it's seem that I miss something and witch diode i should use

could you look at this and should i put diode to y1 y2 y3 since they gonna be all in one point and if im wrong could you correct my drawing please cause like i said im not that good in ic im just at the begining

ok so there no way to get one of those master chip and no way to reprogram one then is there a way to replace by something else??? cause my problem is that I cant get a sgm im on the list for more than a year but no news..... so I try to get the ram to work with my coleco first I try to replace the 2 2114 ram on the coleco by a 6264 chip but that change nothing and now I know that the coleco don't look there for extra ram now I put my hand on a logic module from a adam. then plug in my coleco and its working. remove the 3 rom chip and the 2 6801 chip power on nothing load but when I press reset coleco come on and load game with the extra ram now I want to get rid of the logic board and keep only the thing I need to load the extra ram. cause that thing is ok in the garage but really bad in the living room im not a super tech in computer but im a master mechanic specialize in electrical and a quick learner. can you help me with that little project until I get my sgm sorry my English is not a1 thank

im pretty new in this world of cpu can someone tell me the difference if there is one between the master 6801 and the other 2 on the adam board or they can be swap with out prob thanks I know the master is weld on the board just want to know if there something special in the chip

ok ill give a try to clean up everything first cause that thing didnt see the light for a least 20 years if the clean up dont work do you know someone who repair adams computer on this board.... and this computer have been use only for colecovision when i was 10 or 12 years old nobody play inside or install hard or software on this computer

i guys my message is off topic but I need help with my adams computer ok everything start when I receive my super zaxxon game from teampixelboy and no news from opcode for my sgm so I remember that my father still have the adams computer but when I start it come alive but the screen is all mess up help

add me for ntsc
