RE: Computer in storage - several years - dead motherboard - lost sound recording software.
Carol - find a "geek friend" - explain the situation with your old computer.
My guess is... that for a $10 ni/cad battery (and a six pack with home cooked meal for the geek while he plays around) ... you can resurrect your old beast.
The information IS there - you can even swap your old hard-drive (with the software you are familiar with ) into another machine.
