I've been using the Proflash 89 programmer purchased through www.8052.com, however have hit the wall when I find that it's unable to program the Phillips version P89C52, but is able to program the Atmel 89C52 due to a few reasons. B'coz i do not have anymore Atmel chips available & only have the Phillips, can anyone tell me how I could go upon programming the Phillips P89C52 easily.
