In general, all my PIC stuff has only +5V on the board, so damage possiblity is limited. Recently I had a 16c74a driving a serial DAC driving a 4051 demux, driving a 324 op amp. Accidentally shorted the +15V on the 324 to an input, blowing the 4051 and the DAC. Luckily it did not get back to the PicMaster!
