Anyone know of a good place to sell / resell / donate (as in to a tax-exempt organization where I'd get a receipt) old computer hardware?

I'm working on cleaning my office out, in preparation for a new desk, and I apparently have been working on a museum. I checked a couple of things on Ebay, but the prices for stuff that's this old are not worth bothering to post them.

Some of the things I have (I'll probably edit this list over the next week - I have a lot of stuff, and I'm hoping to take some time off of work to clean more thoroughly):


Colorado Memory Systems Trakker 250 tape backup system

• Parallel Port


• Model JT20CII, manufactured 23 Sep 93!


• Includes power supply, Parallel interface cable, and a really nice padded nylon carrying case

SyQuest ez-flyer 230MB Removable Cartridge System (removable hard disc cartridge)

• I think this one is a Parallel port model, but it could be SCSI-I 25-pin, I suppose


• Part #29003 (circa 1996)


• Includes power supply and a really nice padded vinyl (leather-like) carrying case


• I've found two of the 230MB cartridges so far (and it's compatible with the old 135MB cartridges)

SyQuest EZ-135 135MB Removable Cartridge System (removable hard disc cartridge)

• This one is definitely SCSI-1 (with Amp-50 connectors)


• Model: EZ135,EXT,SCSI,CSTM Part #S982136-001 (circa 1995)


• Includes a power supply. No case.


• Haven't found any cartridges yet

NEC MultiSpin 3Xp Plus CD-ROM Reader

• SCSI-II, Micro D-50


• Model CDR-401, manufactured October 1994


• Includes a power supply, as soon as I figure out which one it is


• This was the 'cool' model of the time, where you press the OPEN button and the lid lifts up

CenDyne External CD-ROM Reader

• SCSI-1, Amp-50 - originally for a Macintosh


• Model: CD|CD 10045


• Includes power cable (the power supply is internal to the chassis - this thing is fairly big)

Some of the other stuff that may make the list:

• A Plextor Ultra-Wide SCSI CD-ROM (Internal)


• An 80MB Apple Macintosh SCSI hard drive (3.5 internal - full height)


• Maybe a Macintosh IIci (haven't decided if I want to part with it yet)


• Assorted cables, SCSI adapters, other adapters, etc.

All of this stuff worked the last time I tried it (which in some cases has been a number of years...).

Anyone have any ideas how I can get rid of it, and at least get something out of it?
