JonnyMac,

I'm questioning if there may be something wrong with the DEBUG circuitry in my SX-Key. When I run your 24LC512.sxb using DEBUG the results state: eeWord 271 even if I uncomment the other comments in the MAIN routine (e.g. PUT_EE 0, 0, $FFFF
  eeWord = GET_EE2 0, 0  ... etc.).

I also noticed that you have OSCHS2 set at 20 MHz. I thought that you can damage your SX-Key if running DEBUG with a resonator installed. 

I even changed the statements to:

DEVICE          SX28, OSC4MHZ, TURBO, STACKX, OPTIONX, BOR42
FREQ            4_000_000
ID              "24LC512"

and did not use a resonator either time and still got the 271 answer for eeWord. 

If I run other programs like EEPROM from you or BEAN I got the same answer everytime even if I changed the value and the address. 

I then decided to run a program you wrote for the Basic Stamp to test the EEPROM itself. I used both a 24LC32A and a 24LC128 and they both seemed to PASS. The program was 24LC32.BS2. 

I did follow the wiring as per the SXB Help 1_51.pdf (page 82) and also tried the I2C example and did not get the results I would expect. I tied pins 1-4,7 to GND and pin 8 to +5 along with the (2) 4.7K resistors to +5v and the other ends to SDA and SCL respectively. 

Is there any other test I can use to make sure that my problem is not with my SX-Key? My SX-Key is fairly new and I know not to insert a resonator in when using DEBUG.
