You still have to coax the BIOS to accept the geometry of the drive (the Portable 386 doesn't support a "user customizable" drive "type")

A better question might be, "why would anybody pay $50?" )-: I'd take $50 for one of mine in a flash.

The trick, of course, is to match those in need to those having the items in question. I'm always amazed when I see power cords selling for $7.95 (do people actually *pay* for them??!)

The bid-ask spread on $50 is at least $37.56 and may even be $50. (You can buy Picstarts in quantity starting at $12.44.) Caveat emptor: ebay. Thank you, -- Don Kuenz KB7RPU
