Does anyone know how to convert this hex program file back to asm so i can be able to burn it to other chips? You see i read another chip for wich a program i would like to copy and i saved it..... but, when i tried to write it to another it did not work......would anyone know how to disassemble the hex code to determin what needs to be changed to complete my project?

My programmer software, WinPicProg, will disassemble it, here's the resultant source code - which looks a little strange?.

:wink:

It took me a while to twig..... but you know why the asm looks weird..... the hex is from a code protected 508x, the first 64 words are never code protected (remember this if you are selling a 508 with less than 64 words).

egg0900, you need to read an un-code protected part..... if I was a cynic........ 8)

Hope this helps
