I have these 5-1/4" diagnostics disks but no need for them. If you're
interested, I'll send them to you for the cost of the postage from
Durham, NC.
* Diagnostics for IBM Personal Computer AT, ver. 2.03 copyright 1981, 1986
maroon disk label, p/n 6183111
* Advanced Diagnostics, ver. 2.20, copyright 1981, 1986
dark blue label, p/n 6139804
They are in excellent physical condition. Sorry, I don't have the manuals.
(I used to work for a ComputerLand store in '81-'82 and probably
acquired them there.)
They might be available for download somewhere, but these are the
physical, displayable versions.
