Here's the thrift report from Everett WA this year....
Goodwill here seems to be cutting down on the amount of computer stuff they carry, as well as the age of the stuff seems to be getting younger. A few years ago, I stocked up on PILES of AT, AT/XT, and quality PS/2 keyboards, and even found an XT keyboard around that time as well, since then, I've started finding more and more modern cheap rubber dome PS/2 and USB keyboards, most of which are the same pack-in's found at Wal-Mart, and most of which are apparently also ditched brand new. I've also been hoarding all the Serial Mice I can find as well. The newer Goodwill is the worse of the two, the other one seems to still carry vintage video games far more often.
Value Village on the other hand, has been a golden epicenter this year and last year for finding older IBM compatible gear. Thus far, between 2006 and 2008 I have found......
- At least 10 AT keyboards
- IBM PS/2 Model 30
- IBM PS/2 Model 59 SL/2
- Holt Office Systems 486
- Macintosh SE FDHD
- Macintosh 6400/180
- AST Premium 386 SX
- Olympic Computers 486 tower
- Several generic AT towers with 486 era parts in them (despite being Pentium II level)
There's another place down near the DMV called "Liquidation Store", which still has an IBM PC 5150 Power Supply for $20.00. There have also been 486 VLB full sized AT EISA boards, Pentium boards of both Socket 5 and Socket 7 design, I also got an AMT 486 from there, and another generic 486 from that shop as well. Their prices however, are kind of steep at times for old hardware, but they tend to have the most interesting stuff including "build it yourself" memory SIMM modules (30 pin), lots of connectors, and various other hardware.
I have not checked out the Salvation Army in Lynnwood in a long time thus far, and usually they are not too good for vintage computer hardware. The oldest PC I saw there was a Packard Bell Legend Pentium I based system with Windows 95, however, they did have a redeeming quality in having Microsoft BASIC for the Macintosh on 800K Diskettes, and a whole slew of 5.25" 360K Floppy Diskettes for my Tandy 1000s both new and used, and some with interesting software on them.
My present haunt for vintage PC stuff is a place called Rich Man, Poor Man computers near the mall. They don't get AT class machines too often back there, but I do find them once in awhile, take them home, and cannibalize them for parts for my older AT class machines, since a lot of those Upgraded Pentiums and K-6's they get in were once 286-486 based machines at one time.
