If everything is connected as specified, there is certainly a mismatch in the electrical connection that you did not see, us neither; or even if it is properly connected, the wiring should not be short enough to provide sufficient signal integrity for the recording speed. In addition, if the chip is not supported by the programmer software, surely an incorrect signature message will appear at some point and you will not be able to go ahead.

As Ctownsend has pointed out At89Cxxx chips can't be programmed using ISP programming.
it is easier and cheaper to get correpsonding A89Sxx chip as a direct pin to pin replacement.




AT89C2051 does not use ISP programming. AT89S2051 does.

If you have an AT89C2051 you need a parallel programmer something like this:
