And I have:
Two bookcases full of boxed software (including OS/2 Warp 3 *and* 4 as well as an (unopened) copy of the Brief editor as well as loads of games)
Several boxes of misc hardware - 3com network cards, various SCSI 1 and 2 cards, sound cards, and (maybe) a Voodoo graphics card as well as a couple of ISDN cards.
Several bits of Sun hardware - Sparc 1 and Sparcstation 5 bit as well as SCSI cables and drives (100 Megabytes! Ohh the space!).
A Sun 17" CRT monitor - still in use on the odd time I need to see the console of my virtualisation server.
Various piles of old drives (mostly non-working of so small to be of no practical use).
Pretty much all the mobile phones I've ever bought from an old T-Moble M2 (Windows CE) to a Palm Treo (PalmOS) to a OnePlus 3. All in pretty mint condition.
A Nokia 770 and 800 and an Apple Newton - again, all still working..
I keep meaning to sell it on Fleabay but can't actually get the energy to do it.
