I MUST HAVE A PROGRAMAR FOR THE 8051 89C51 AND 80C2051 AND 89C8056 WITH USB PORT FOR THE COMPUTER. WHEREIS THE SHEMATECS FOR IT AND THE CODE?
the programming algorithm is different for NXP 80C51 and Atmel 80C51 and intel 80C51 and ...
A 'universal' programmer is expensive, for some specific chips there are cheaper solutions.
saying 80c51 say diddlysquat when it comes to programming.
