I have some Eprommer at home and in the company I am working for and
I have quite a lot of Eproms.
So what I need:
1. Which type of Eprom is needed (I don't want to open my AN1X before I
don't have the eprom with the new version in my hands) ?
2. An eprom with V1.04 in it or a binary or Intelhex or other file with
V1.04 in it.
Can somebody help me?
Ciao
