I noticed a bunch of MZ stuff on E-Pay last nite. Based in the UK.
Also an UK MZ users group this led me to.

  Does anyone have a working boot disk for a Sharp

 I went to use mine for the first time in a few months, and all of the
 disks are either reporting "Not a Master" or "Read Error". Since I
 *know* that at least 3 /should/ be bootable[1], there is clearly
 something awry with either the disks or drives. I'm going to try my
 spare set of drives tomorrow, but if that doesn't work then I'm stuck :(
 TIA
 [1] One of them I made myself, used it, and even labelled it "80B Boot
 Disk". And that reports "Not a master" now. Grrrr. :( -- Cheers, Ade. Be
