 I just saw a manual for DOS2.11 in a local thrift but wound up leaving it
behind by accident. I hope it's still there when I go back. It was labelled for
Toshiba.
 I have the 2nd edition of "DOS Power Tools" ISBN 0-553-35464-7 . It covers
DOS up to ver.5.0 . 3disks and some newer utilities. Quite a good book.
