I completed my driver routines for the 24C512 EEPROM.   I have attached the files.  I now realize that there is a lot of information available on the I2C bus, which is the protocol used by the EEPROM chip.  Günther's SX book has an excellent tutorial on I2C.  I am still puzzled by the transition from the ACK bit to a START or STOP, but I got it to work by adding an extra clock cycle after the ACK.
