I bought a Wallstreet PDQ 300mhz at a thrift store last year for $35. It has a bad screen hinge, dead PRAM and main batteries. It has sat on a shelf for most of a year because I did not want to damage the display cable.

I finally ordered a set of hinges for it last week and am eagerly their arrival. I can do without the main battery for a while - my Lombard's battery works great if I need a portable Mac - but where would be a recommended place to get a PRAM battery?
