In my locale the tash "service"furnishes ,as part of the monthly fee, oversized plastic bins with lids and the commercial accounts get big steel bins,some with LOCKS!
Dumpster diving is strongly discouraged and may even lead to criminal charges!
About the only way is if someone actually places the item out curbside with a free notice or one happens to get permission from one's workplace(and that isn't easy ,what with "corporate ethics" policies ansd security policies that suggest anyone wanting discarded items is of questionable character and intent!)
I did get a nice stereo amp that needed only a fuse,but that was 20 years ago.
Better luck finding the odd bit at thrift store of yard sale.Once got 8 64s for 50cents each.A friend found an Amiga 1200 for $12 at Goodwill!
It is a sin and a crime against the poor how much usuable stuff goes to landfill,not just Amigas.
