can you read the 89C2051 with another programmer or is it damaged?
if you explain what programmer it is or where you got it maybe someone has the software for it?

Can you post a schematic of the programmer?

i have a physio therapy unit TENS, I have a to device. one is damage and another is ok. and when i replace the damage ic into fine device, the device stopped to work. so im conform that 89c2051 is damage. so i want to copy fresh 89c2051 to another blank IC.

You can't use a different IC without doing any modifications on the program i.e. if you have it... find the same IC if you're to replace!!

Use a 'programmer' to copy the information on the IC.

I don't have a any programmer so i want to make a programmer which can easily copy the ic.

You need a programmer to read from the IC!!! that is if the information on the IC is not protected!!!

This is by far the best and easiest & most reliable programmer for the at89C2051.

**broken link removed**

follow the schematic carefully and you will have a good programmer.
If your PC does not have a serial port, you can use a good USBtoRS232 cable (not a cheap knock-off from China!).

I suggest to use this programmer for 89C2051 :

https://epraktikum.iz.rs/projekti/atmel/atpro.php

Programmer PC software, PCB and rest informations are on that location. Programmer is free to make and use for noncomercial usage.

You have PCB on project address, trace routes. I think its not hard job. ;-)
