Well i think its Illegal...! as far as i know. you need a written concern from the manufacturer or something like that..
Just a hint.. you need to open the IC and and burn the locks.. [ i saw this on a site ]

Does anyone have microcontroller programming software for STC15F104W (core 8051, 4 k, 128 byte, 6 I/O pin, UART ... DIL8), that works?
