Functional expansions

Alternate interface
Machines that alternately use a second punching unit or a comparable medium can be
switched over to a second I/O pair.
The second I/O pair can be defined via the following machine data:
MD26004 $MC_NIBBLE_PUNCH_OUTMASK
MD26006 $MC_NIBBLE_PUNCH_INMASK
The interface is switched by command SPIF1 or SPIF2.
Full punching/nibbling functionality is available on both interfaces.
Example:
Hardware assignment for stroke control
Define the high-speed byte in each case on the CPU as a high-speed punch interface:
MD26000 $MC_PUNCHNIB_ASSIGN_FASTIN = 'H00030001' → Byte 1
MD26002 $MC_PUNCHNIB_ASSIGN_FASTOUT = 'H00000001'
Remark:
The first and second bits are inverted.

; At the end of the block, a stroke is initiated at
; the first high-speed output. The "Stroke active"
; signal is monitored at the first input.
; The second stroke is initiated at the second high-
; speed output. The "Stroke active" signal is
; monitored at the second input.
; All further strokes are controlled with the first
; interface.
