I have this Amiga 600HD and on the interface for the 2.5" internal hard drive one of the middle pins is missing. It hasn't broken off its a clean hole. Was there any chance that this was always the case. Can't see why.
Looks like drive activity LED, I assume that normally activates the a600 hd. Maybe the previous owner wanted to use the led for something else?
