I see all sorts of obsolete digital recording gear at the thrift stores, you are not alone.
I forget what it was but I recently saw something that looked interesting but it was Firewire 400, pretty 2006-ish.
FWIW, Waveform Free is a really nice and easy to use DAW that is 100% free. Go to www.tracktion.com
, click on the products tab at the top, scroll down to the free products tab and grab a copy. Even if you dislike it you can just delete it. They'll get your email but they don't send much, just sales about 4-6 times a year.
