Awhile back there was talk here about getting the documentation for the classic machines as while as the machines themself. I picked up a IBM Guide to Operations manual 6025113 Dated 1981,1982 and listed as the First Edition. In the back was a clear plastic bag with a casette tape for Diagnostic's number 6081562 version 1.02 new and unopened. The book cost me 50 cents at the Goodwill. Also got a AMIGA monitor I believe a 1080 for $15 at Goodwill. I also won the bid on a very large bo full of computers, parts, TV's, microwaves, and other items for 35.00 will list later after I sort it all out. Keep computing !!! John
