AT89C2051 does not use ISP programming. AT89S2051 does.
If you have an AT89C2051 you need a parallel programmer something like this:

Hi,
thanks for your post.
However that is not the same atmega fuse doctor as in the link I posted.
I think I found what I am looking for earlier today.
Thanks
Hello everyone,
I am just looking for the source code in asm or the Bascom file for this programmer.
**broken link removed**
I see the hex and bin files but no source code.
Anyone?
If there are any C51 assembly guys still out there:
I found a solution to this thread (which is now closed)

download the program here:

It works with windows X64.
Thanks to Ronton for bringing it to my...
Hello Guys,
I am trying to program an atmel AT89LP6440. I built the AT89LP ISP Studio programmer board form this link here.

I know my connections and everything are 100%. Just can't seem to get anything to work. I tested on an AT89S51 (so there...
Well you referenced atmega8. AVRStudio4 supports atmega8 and many more devices. I am not currently using any device that AVRStudio does not support.
If I do in the future there are ways around that.

Get a logic analyzer. Measure the output of the remote. Then connect the logic analyzer to the output pin on your microcontroller to see if it is doing what it should.
This is working, you will have to change your pinout to match this code, OR
change the code.
ALSO: in your schematic, you do not have a resistor connected to pin 3 on the LCD. You should install a 10K pot
so you can adjust the contrast. Without this you may never see the test and you may think...
