Yeah Chuck, that Samsung is definitely one of the easiest to mod for 8" emulation and documentation is actually available; as a matter of fact I think I'm the one who first suggested it to you when you were looking some long time ago since some of us Cromemco users had been using them for a while.
But the bezel layout is a little critical here; the drives have to fit into slimline 1 1/8" x 5 7/8" 5.25" drive bays/adapters like Compaq used in some of their servers and portables (although they're actually going into a Commodore PET), and the NECs are indeed out of a couple of Compaq servers.
I could probably kludge the oval eject button and whatever else needed to make another drive fit, but I wanted to play around with modding other drives for 8" emulation anyway while I was at it.
I think I may have enough to make them work, but thanks for returning the tip ;-)
