I still have a 14k ISA modem card in a box in the attic....... Along with a remarkable collection of other antiquities. I've few of the original 386 and 486 wafers from Intel, and enough old processors to melt down for wedding bands, if gold ever gets scarce. My favourite is an Ericsson 'mobile' phone from the Lisa era- it was mobile insofar as you theoretically could move it, if you were strong enough. Damn thing still saved me once out on the North Sea while I was fishing- and not paying attention to the weather. I really need to do a clearout- I did a massive donation to a teacher training college in Kenya a few years back- time to do another, I fear.
