I work on plasma etchers at a small semiconductor plant and I've got a tool (Drytek 384T) that uses an old intel 8751 microcontroller in the RF match controller. I've never messed with programable chips before, so this is all fairly new to me. The problem is we have several identical tools but each one has different versions of software in this eprom and only one of the tools actually works well. I don't have the source code (wouldn't do me any good if I did since I'm not a programmer) so I wondered if it's possible to copy the software from one chip (like a hex dump or something like that) and use that info to program an indentical chip. The P/N on the chip is P8751BH. Also, what type of software/programmer would I need to do this if it's possible. Any information that anybody can give me would be greatly appreciated. Thanks.
