I've got an old 2600 system, the original with the wooden front. Bad thing is that its about 1500 miles away and I am working on a 3D rendered version of the system.
IF you have a digital camera a 2600 6switcher and a bit of free time please reply here or send me an email at armature@zerosignal.net...I cant pay you, but I'll give you a finished rendering of the system.
