True - VICs (unlike TEDs - grrr) were very rare to fail, although I saw some with various "special effects" over the time.

Means you haven't experimented much with the CASSETTE port of the 64 ;-) I myself fried one 6510 when doing things there. Obviously it counts as human error but it was harder to make such in case of the VIC, which sits well behind reach of a CU.
