Thanks for that Mark.  I've learnt something today <grin>

Actually, I do pop into a fair almost every weekend. (I get into them
free.)  Very few traders do secondhand stuff, and usually it's more like
VGA cards.  Second hand hard drives are almost always SCSI.

I think the very low prices of current IDE units has made traders decide
it's not worth trying to make money on MFM/RLL units.

I find radio rallies much better for this kind of thing.
