Consumer electronics is my downfall. I’ve got a complete PC of Pentium 3 vintage (which I can’t throw out cos it’s got a BX motherboard, kill me now) along with various parts that ‘might come in useful.’
I’ve got a load of AV kit which got decommissioned when I upgraded everything recently; so, AV receiver / amp, twin cassette deck, high-end VCR, laserdisc player.
Loads of pocket electronics including several Palms of varying ages, my beloved Psion 5, and more phones than I have ears.
A surprise drawer of mystery power adapters. A large bag of assorted cables, which TBH is the most useful thing of the lot. If anyone ever needs to wire up a Ford Anglia to the Hubble telescope, I’ve probably got the cable to do it.
Tamiya R/C car and assorted toys dating to childhood; original Big Trak, Scramble, Firefox F-7, a non-functioning Astro Wars (*why* am I keeping that?!) and odd sets of Lego.
That’s off the top of my head. I feel an archaeological dig coming on.
