I have a ZEOS 486 with peripherals that I'd be glad to give to anyone willing to pick it up within the next week or so at my home in Stow, Mass. The monitor, keyboard, mouse, and computer itself all still work, except that the hard drive ceased functioning some months ago (and will be removed)...
At my office in Westford, Mass., I have two North Star Horizons, one with the original "thick" wooden cover -- see picture at

-- and the other with the later thinner wooden cover. Neither boot with the disks that I have, but the drives rotate...
