In each model, there is cpu. There is also graphics output consisting of Antic and GTIA processors. For sound output, the Pokey processor is used. PIA takes care of joystick ports. MMU, EMMU and FREDDIE are for memory management. Operating system and Basic are stored in ROMs. Various other stuff is described here. System boards and their layout is given here. 65XEM prototypes contain AMY chip for super-sound. Following is the list of all the released models in 8bit line. If you want to help me make this list complete, open your computer and report me: the model and its TV norm all the COxxxxx numbers on all the parts (Uxx number, manufacturer, date YYWW) don't forget to add crystal values and C0xxxx numbers all the numbers on the board number of memory chips (also note empty space) all the connectors, switches etc. Computer models 400 800 My 800, NTSC.
