Hallo Laze, > I even tried typing LOAD"$",8 (a few times actually, to > make sure I didn't mistype anything). So if you type something, it doesn't show up? IIRC the 40/80 column button is read by the CIA as well. No IRQ -> no reading of the keyboard -> no mode switching + no typed chars on the screen. Again: CIA (or CPU). > The normal start-up sequence. For sure: this means the rattling of the drive as if it is looking for something? This would mean that one CIA is OK. @all: does sending commands to the drive also involve the need of IRQ's? Being very familiar with drives doesn't mean being familiar with the sending protocol as well :) If IRQ is NOT involved: again CIA. If it is, it would mean that an IRQ is generated. Generated by the CIA that should read the keyboard. A CIA with a completely brooken port could cause this behaviour (I had once a 6522 behaving like this). > ... that I try to leave as few fingerprints on it as possible. > Using saliva is out of the question. :) Bill is not asking you to spit on it. And so far it seems you have to desolder the keyboard CIA, which means a lot of fingerprints..... -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| URL: Ruud.C64.org De informatie in dit e-mailbericht is vertrouwelijk en uitsluitend bestemd voor de geadresseerde.
