In total I already bought 2 Colocovision Consoles + Adam Computer expansion module 3 incl. printer, keyboard and replacement keyboard, tapes, manuals etc. etc. both sets as untested. I already got a new powersupply and waiting for the RGB mod kits - if the controller chips are faulty (replacement chips already ordered if...) both NTSC. At least I need one Colecovision + the Adam Expansion running. Are there any good manuals for testing / fixing and maybe other easy mods? Bought a "cheap" untested Expansion Module 3 - cheap yes don't ask for shipping + German import taxes...

I might be interested to purchase one diskdrive - depends on price

No, but I will rebuild a second one this weekend.

Got my Sears Arcade II today, machine fires up so for now I need an AV mod. Any recommandations? Or a nice manual for using 2600er A/V mods soldered on it?

tried on my other Atari 5200 this diy mod, but the only thing thats works is audio out... I tried this schematic, but no luck http://retrogame.cyberphreak.com/2017/06/05/atari-5200/maybe somebody has done this successfully and can send / show his soldered pcb (both sides). Thx... Still in the thinking to throw it all away and keep only the commdore stuff

Well this one I plugged into my 5200 4port and getting only a black & white screen, no coloured one. Via antenna cable the screen is coloured... still no solution why...

Nobody has an idea?
