So Darrell,

My ultimate goal is to get 256 word variables into the EEPROM chip from a comma delimited text file in decimal. My plan was to put them into on-chip EPROM first in 128 word chunks then read them out in a loop and write them to the external EEPROM chip. This is pretty tedious though. So I'm wondering if you have any thoughts on a way to simplify the process?

Once I have the chip programmed, I can then read it out to create a file for burning them in production. Wish I could just get the data directly into my PROM burner...

BTW This is a temperature look-up table for a thermostat type device. The values are ADC readings for the degrees F from 0 to 255.
