hi ved,
if the resistor array in question is being used for pullups of the uC then the SIP used is internally connected as shown in figure. U can create ur own SIP using individual resistors of the same value in a similar configuration.





oops , looks like sunrom and i posted at the same time. ... Read Compelte post

You can use general resistors instead of the array..just buy the same quantity as the SIP array.
You could use regular IC socket for the zif if you can stand the inconvenience of pulling out and shoving in chips multiple times.Could result in damage to the chip too,if not pulled out carefully and contacts could go loose after several attempts.
Better get a ZIF socket from some online sources(Sunrom,... Read Compelte post

i have seen your replica of I2C programming using AT89C51 but i am unable to understand the "ack_bit" variable usage ...looks like it is always 1...can you elaborate how acknowledgment is working....

Pins high is the normal state. You need a program to set them low
