It seems that almost every other time I try to boot up my beloved PowerBook Wallstreet, It Gets a system error opon startup. The description of the error said it was a "bus error". I try the reset key combo, but it doesnt work so I have to unplug it (it has no battery). The other problem I have been having constantly now, is that, left to right the one to zero keys, and the q to p keys dont work at all. It used to be ocasional, but now it seems to be happening all the time for some reason. Maybe do I need to replace the keyboard? and help or ideas would be greatly be aprieciated.
