A couple of items I've had given to me by my customers, and not just computer equipment too, some of them know I'm a radio nerd so I get offered bits an bobs like that too.
My last few notable donations, a mint pair of Ruark Hi-Fi speakers, A Musical Fidelity P170/P172 Amp/Pre-Amp combo, Meridian CD200 CD transport with CD203 DAC.. Amiga 2000 with various cards, BBC B (Must dig that out of my mates barn. At the time I was short on space and put it there "for a few weeks." This was nigh on a year ago...) , Amstrad PCW9256 (I think it is), and my CBM PET complete with 4040 floppy drive unit, a load of brochures and magazines from that era and some floppy disks.
That PET was a laugh, all that gear weighed a ton as you can imagine and the bloke who insisted I can have it also insisted on bringing it all to me himself. He's nearly 80 and must weigh about 6 stone dripping wet.
