I have an 80C51 equivalent IC chip, P80C521, and i think it has internal either 8 or 16K of ROM. no external ROM on the board.
Im familiar with Atmels and programming of atmels, but can someone point me in the right direction for a simple programmer/reader for this P80C521 chip? the chip is a display controller, no datasheet available for the display, so I need to dump the ROM so I can run it in a disassembler.
any ideas? thanks.
