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 NIBBLE_PUNCH_OUTMASK
MD26006 NIBBLE_PUNCH_INMASK
The interface is switched by command
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 PUNCHNIB_ASSIGN_FASTIN = 20002H stroke control 2.EB (MCP) inverted
MD26002 PUNCHNIB_ASSIGN_FASTOUT = 2H stroke control 2.AB (MCP)
Remark: The first and second bits are inverted.
Screen form for high-speed input and output bits:
MD26004 NIBBLE_PUNCH_OUTMASK[0]
MD26004 NIBBLE_PUNCH_OUTMASK[1]
