 		 #34402 - RE: In-System Programming (ISP) from EEPROM
Just use parrallel EEPROM and ground !EA, program them and you can change the program all you want. In this scenario forget all abt ISP. OR use 2 P89C51Rx2 with ISP use internal code and just replace the processor, the you can have your cake and eat it too.
