AT89C51 24PI Programmer

Considering this is a site for AVRs not 8051s....... What exact programmer do you need? One that programs 89C51s of course. I have a HILO ALL07 programmer that does them. There are many others I expect, the problem is you're about 20 years too late.

Do you have shiploads of very old parts ? What is the full part number ? If it is AT89C51RB2/RC2 (the suffix letters matter) those I think have bootloaders inbuilt, so are easy to pgm. (as do newer AT89LP51RB2..)
The very first generation 89C51/52 needed Vpp FWIR + Parallel pin loading, but in 2019 the newer ISP ones are cheaper..
The SP200S (bare board module) mentioned above should support it, and if you need an active/supported programmer with new devices, the TL866 is looking good. (cased ZIF USB )
I have this very old micro-controller and need to read back the code in it as hex file. the complete part number written on microcontroller is AT89C51 24PI.

So SP200SE USB Programmer is the one that I can use for program reading and programming?
Where can I find its driver and tools?
@joeymorin any way to check lockbits please?

Thank you for the suggestion, my controller has the suffix 24PI, that is AT89C51 24PI. So SP200S will work? Any driver needed?

Yes, there will be some EXE file you download for SP200S, and a locked chip will read as all 0xff - usually, you can expect a production chip to be locked, so you may not get the HEX you want.
