Keyboard Scan Codes - IBM XT 5160 Technical Reference

Keyboard Scan Codes
Each key is assigned a base scan code and, in some cases, extra
codes to generate artificial shift states in the system. The
typematic scan codes are identical to the base scan code for each
key.
Scan Code Tables
The following keys send the codes as shown, regardless of any
shift states in the keyboard or the system. Refer to "Keyboard
Layouts" beginning on page 4-44 to determine the character
associated with each key number.
