"Surowe" kody klawiszy generowane przez klawiaturę. W dalszej fazie obróbki system operacyjny przetwarza większość z nich na kody ATASCII.

Wciśnięcie odpowiedniego klawisza z klawiszem SHIFT zwiększa kod o 64 ($40), a z klawiszem CONTROL o 128 ($80). Niektóre klawisze są niedostępne w kombinacji z SHIFT+CONTROL wciśniętymi równocześnie.
System operacyjny bada wciśnięcie klawisza HELP i w zależności od tego ustawia flagę HLPFLG (732, $02DC; zapisywany jest tam kod kombinacji klawisza HELP z ewentualnymi klawiszami SHIFT lub CONTROL).
Klawisze F1..F4 są dostępne w modelu 1200XL.
Układ sprzętowy rozpoznaje wciśnięcie kombinacji klawiszy SHIFT+CONTROL+A, aczkolwiek system operacyjny rezerwuje jej kod (255, $FF) dla oznaczenia w rejestrze KBCODES (764, $02FC) stanu, kiedy żaden klawisz nie został wciśnięty. W konsekwencji wciśnięcie tej kombinacji może być wykrywane jedynie bezpośrednio w rejestrze KBCODE (53769, $D209) lub przez własny handler przerwania klawiatury wektoryzowany przez VKEY (520, $0208). Praktycznie użycie tej kombinacji może służyć do "oszukania" systemu i anulowania informacji o ostatnio wciśniętej kombinacji klawiszy.
Wciśnięcie klawisza BREAK powoduje wygenerowanie przerwania IRQ ze skasowanym bitem B w rejestrze stanu procesora (analogiczne przerwanie generowane jest za pomocą rozkazu procesora BRK, lecz bit B jest wtedy ustawiony). Systemowa procedura obsługi przerwania klawisza BREAK wektoryzowana przez VBRKKEY (566=$236) ustawia bit 7 w rejestrze IRQSTATS (17=$11). Przerwanie rozkazu BRK jest wektoryzowane przez VBREAK (518=$206).
Dodatkowa informacja o wciśnięciu bądź zwolnieniu klawisza SHIFT lub dowolnego innego klawisza (prócz BREAK, CONTROL i klawiszy konsoli) może być sprawdzana w rejestrze SKSTAT (53775, $D20F).
