We get in GoVideo dual deck vcrs that use those eproms. Usually the symptom
is no audio and the video headswitching is about 180 degrees off. Reprogram
the eprom and all is well. Unplug power and we are back where we started. We
have had to replace the eprom on every one of those. I think we arte really
just reprogramming the micro, which sends that data to the eprom, and just
loads it back to the micro after a power interruption.
