Good info about the various adapters and batteries. I just bought a Gossen Super Pilot cheaply. I believe it uses the same battery.
Would those same methods work for a Minolta SRT? I've been using my 101b's and 201 without a battery. It would be great to have a working meter in camera as well as the separate hand held meter.
Perhaps the Gossen will be more accurate than the SRT's would be.
I'm not sure how much help this would be, but I once fired up an old Minolta X300 and had to put in new batteries to get it working - I think it was those same kind of batteries, the meter was working fine (although I may be wrong as I was only starting out in photography at the time).
