i'm trying to fire up the old Heath H-120. it seems to have "forgotten" how to see the floppy disk controller, i get: DEVAULT DEVICE CONTROLLER ERROR i've checked quite a few things (e.g. reseat card and chips, look for cold solder joits, etc. - see my more extensive posting on comp.sys.zenith.z100). it seems like maybe getting hold of another H207 card (floppy controller) would be worth trying - or maybe even a whole Z100 system for swapping parts. are these still showing up at auctions? (DOD was of course a big Z100 customer). How do i find out about these auctions? anyone know of a source for spares or help with this sort of thing? thanks. - glenn +=========================================================+ | Glenn F.
