The code isn't mine, but it was generated from a HEX file by an old version of my disassembler, notice the date is 1998.

OK Thanks for the reply-this asm is part of G.O.L.D.P.I.C 3.01 metaldetector

As he's selling pre-programmed chips, it seems strange he's not code-protected them?.

 

[GrimRipperVT]

Nope im sure they are code protected since he started selling them,but
the code is known by some people incl me 8) I found this good forum and i saw your posts,so i decided to write-many times ive wondered who is Nigel Goodwin!?Is this code his work?
Nice day!
