What's a 24C05 ? It rings no bells with me.
If you have a programmer that can program the 24C04, then it will program the
24C05. The only difference between the devices is pin7, which on the 24C05, is
a write protect that, when tied to Vcc, protects the upper 2K of address space
(so that it functions as ROM space). On the 24C04 device, pin7 is NC.
Of course, to program the device, it should be out of circuit, removing the Vcc
from pin7, and enabling the device to be written.
