FSTICD==:540 ;FIRST INTERNAL CHANNEL DEVICE CODE
LSTICD==:574 ;LAST INTERNAL CHANNEL DEVICE CODE
;IN THE IDEAL WORLD IT WOULD BE POSSIBLE TO INSTALL THE NIA20 OR CI20
;IN EITHER OF THE MODIFIED INTERNAL CHANNEL BACKPLANE SLOTS IN THE
;KL-10. UNFORTUNATELY, THERE IS NO EASY WAY TO TELL THE TWO TYPES OF
;DEVICES APART. THOSE WHO ARE FOOLISH ENOUGH TO BELIEVE THE
;DOCUMENTATION MIGHT DISAGREE, BUT THE ENGINEERS NEVER STRAPPED THE
;NIA20 AND CI20 TO RETURN DIFFERENT PORT TYPE FIELDS AS THE
;DOCUMENTATION LEADS ONE TO BELIEVE. FOR THIS REASON, THE SOFTWARE IN
;TOPS-10 HAS BEEN WRITTEN TO ASSUME THE NIA20 CAN ONLY APPEAR AS
;INTERNAL CHANNEL NUMBER 5, AND THE CI20 CAN ONLY APPEAR AS INTERNAL
;CHANNEL NUMBER 7.
