I just don't understand where it went. It's not something I would think should just disappear
I installed the Calibre portable 1.48 on my other PC (just so I wouldn't get confused as to what was what), copied the "calibre" folder over, but when I click on Preferences-->metadata plugboards nothing is there.
I guess I will just try to manually recreate it. However, I do not see a listing for the PRS650 (the PRS505 is listed as is the PRST1) there is no generic listing for Sony. So what should I choose as device?
