Upon close examination of my sx-64, I've noticed that the clock signals are generated by a small pc-board mounted to the cpu board. I can understand this, as it makes it possible to build a PAL signal generator, as well as an NTSC one, and not have the headaches of needing a programmable clock gen that cna do either taking up board space. WHat I don't understand is why there are two crystals on this little board. The top one is the normal ntsc 14mhz crystal, and the bottom one is obscured, soldered to the top crystal such that it cant be seen. anyone have any clues? :) - This message was sent through the cbm-hackers mailing list.
