Do you have a X28C64P-20 for U500? You can compare its datasheet
with Atmel 28C64, if it matches 28C64 is available at Digikey (and probably other places too).

Hi experts,?

can anyone point me to the specific type of the eeprom U500 in my Hp8563e??
Where can I eventually get a substitute/equivalent for it? I suspect it might get corrupt due to elapsed time...?
Any advice is more than welcome,?
