Re: Another ParPortProp Awakens!

Congratulations Jim!

My programmer (a cheap Willem type), does have both 24LC512 and 24C512
in the menu, and once I picked up the wrong type (24C512?!) and it
didn't work correctly, at least the software complained. Looking at
the datasheets, Atmel 24C512 has two address lines, while Microchip
24LC512 has three... Not sure if it would cause any problems.

Thanks,
Sergey
