okay.. thank you :)

may i change the transistor bc557 in the schematic from this link -> h**p://chaokhun.kmitl.ac.th/~kswichit/IspPgm30a/ISP-Pgm30a.html with 9012 / 9015 ?

thank you very much :)
 

To be more specific this is called Snatsz, (Wierd alien name...)

Its based on 2051 as firmware IC that programs 89Sxx chips, Works 100% every time for me as compared to parallel port based cable.

Thanks,

Alex
