Hi Paschoal,

I've never had any problems with my Needhams EMP-20 programmer, and have had good support. Even though its software is DOS, Needhams has worked to make sure it still runs even on my Win2K machine.

But that said, I really love those ISP parts where the programmer isn't required! There are enough 8051 variants out there that support ISP that I'd recommend using them and skipping the programmer. Use the money saved on the programmer for a good compiler.
