Memory
The Memory test verifies memory data patterns, memory addressing, and parity detection for all system memory.
Keyboard
The Keyboard test verifies the keyboard inter- face, the individual keys, the LED indicators, the repeat action key mode, and the security lock (if applicable).
Parallel Interface
The Parallel Interface test verifies interface data and control lines, internal loopback control circuitry, external loopback (if a loopback plug is attached), and a shifted pattern of standard printable characters (if a printer is connected).
