[John Lighton]

Greetings. Can anyone disassemble some ancient precambrian legacy 8015 HEX code (target AT89C51) for which the source was lost sometime in the Jurassic, remove a pesky conditional and reassemble it? I'll be happy to pay for someone's expertise in this area, as long as the reassembled code works as needed. Let me know if you may be able to help. Thanks!

Did you mean 8051 machine code? How big is the binary? How much code
are we talking about?

Hi Dave,

Yes, it would be 8051 machine code in .HEX format. The HEX file is 35K in size. If you'd like to take a look at it, I can send it to you off-list.
