You have an original Tandy 1000. The keyboard you need is the
   Tandy 1000 keyboard. *You can get it from Radio Shack for about
   $99, or you can beg it off of someone from this newsgroup,
   probably for about $25-30. Hard cards work beautifully in Tandy
   1000's. You can get a boot disk as well as a copy of the
   original Deskmate for $5/diskette. *My suggestion: Get both
   MS-DOS 2.11 and MS-DOS 3.20. *You won't need any greater
   versions than those. *2.11 has the beauty of taking up less
   memory. *3.20 has many of the extra features you might be used
   to. Good luck! *Your local Radio Shack also has "Tandy FAXback".
   *Ask them about it and see what information they can get you on
   the Tandy 1000 from it. Ken via comp.sys.tandy
