Any one else have problems opening the case to install a battery for the RTC?
Screw will not budge and was half stripped to start. So think it was powered screwed in. It is also a specialized screw and not simple common US type.
As have been into computers so 80's so I have many size special tools none of which fit. Nor could I loosen it via wrench on a screwdriver that at least fit. Now have tried to chisel it out and still has not budged. I am currently slowly cutting case away from head. Once open I will use pliers to get the screw out and replace with oversize head screw.
