100Mhz DSO should be fast enough...although if you're viewing the signals in real time, you still might not see the pulses. Maybe slow the clock WAY down (i.e. 32khz internal clock) and see if you can see anything. Maybe connect the pins to a pulse counter or a freq counter and see if that shows anything. Or a 555 timer set up as a one-shot pulse stretcher (i.e. 1us pulse gets stretched to 1 second so you can see it)...
Have you tried connecting a plain ol' 24LC256 serial eeprom type thing to the PIC and working with that just for grins and see what happens? Then after that works, move back to the other chip?
