The above posts just go to show, even if manufacturers stop making floppy drives many computer enthusiasts will always have some spares lying around. I', sure even when present systems have been superceeded by something new we will still have a couple of the things hiding in a corner. I too have spares which I've been loath to part with for many years even though I no longer use them. Most of my spares such as old graphics cards,MoBo's, cpu's, memory, psu's, HDD's and sound cards tend to get thrown out after a few years simply because they are no longer compatible with newer systems. all my AGP cards have now ben thrown out (apart from a NVidia 7600 GX 128Mb card which I reckon someone could still use if they aren't into the latest games (it's only got shader model 2 whereas most recent big bucks games require shader model 3.0)
Several years ago I tried to set up a hardware giveaway/exchange on the site I used to help run, but over the year it was up only a coule of entries were added to the database.
I still think there's a market out there for older components, but where to find that market is a problem. In the mean time I'll continue to recycle my older components to the bin except of course my dear old floppy's lol.
