Got the V7805-1000 and it works great, provided you don't put it in backwards. 
The diagram I was looking at on the data sheet was apparently a top down footprint drawing and I smoked a Atmega328 and a 7404 in one shot. Oh yeah and as the white smoke was rolling out of the 7404 I noticed the dot on the package. Of course it would be on a Friday and absolutely no one locally stocks them. I have a spare 128 and several 7404's but I needed the extra EEPROM. RTFDS (thoroughly)!
