Not exactly purchases, since everything was free. Recently I had a quite a good day. I'd arranged with an old friend whose health is declining, to drive him from Manly up to Morriset to pick something up. On the way back, in Manly we came across an old Subaru abandoned in the street. Council 'abandoned car, will be removed' stickers, one smashed window, being used by locals as a junk dumping container, has been there for months, etc. Thing is, it's almost identical to my car - 1993 Subaru 4WD station wagon, that I like a lot. Except for the part where the engine needs reconditioning, but I can't afford it. Now extraordinary luck steps in. As I was standing next to the abandoned car, peering in a rear window (it was dusk, light fading) a young guy riding by on a pushbike noticed me. Stopped, and the first thing he said was "Hi, are you interested in that? Do you want the key?"
Ha ha ha... of course I said yes. Turned out it had been owned by a friend of theirs (flat just up the road) who'd been in Oz as a tourist, bought and used the car for a trip up the coast, then went back home overseas. Abandoning the car and leaving the key with his friends. Who weren't into car ownership, and let the rego lapse. So... it's mine now.
Turns out the engine is in great condition, may even have been recently reconditioned. It's identical to my car's engine, exact same class number, swapping is no problem. Even getting the car from Manly to Bankstown area the next day was easy and free. 1st pic is the two side by side (my old one closest.) Given how much I hate cars with engine management computers, and these Subarus were one of the last models ever made without, this is really excellent.
Second windfall: my friend has a long career as a designer of pentium system boards and related stuff. He feels he's unlikely to do any more of that, and is currently living in a small place. After the Morriset drive he gave me a stack of his old tech texts. See 2nd pic. Some of the ones on the left I already have. Anyway, if he does need them again he can get them back. Donating to the TerraHertz tech-archive is better than binning them.
Naturally, the one topic I need texts on atm (Bluetooth) is not among them.
