alternative for currently using 59c11 eeprom

[suman]

sir we r using a control board with d7810hg 64 pin (it is an ADC supposedly).also we have a programmed otprom with a supporting eeprom which is 59c11 (8-pin dip).now this eeprom is very hard to find.some guys advised me to go for 93c46 (also 8-pin dip eeprom).both r 1Kb serial micro wire eeprom.but one pin in 93c46 is dummy which is a ready/busy signal pin in 59c11.how do i replace it? can i modify the otprom program to suit it.infact the ready/busy pin 93c46 is integrated with data out pin .whreas in 59c11 both r different.besides which every thing else is the same.
please help me out.
if some body can tell me where i can get 59c11 eeprom i will be very grateful. * the eeprom is not programmed.
