IBM PC Diagnostics 1.x (Convertible)

These are the diagnostic disks (and cassette) provided by IBM with their PC computers. They are used to verify the basic functionality of the hardware. These are only intended for use with genuine IBM computers.

Diagnostics were included with the IBM PC Guide to Operations manual bundled with PCs. Advanced Diagnostics were included with the IBM PC Hardware Maintenance Service manual, which include more testing options and hard disk formatting support.
