This is the standard card reader.
This is the standard card punch.
Input formats are accepted in a variaty of formats:
Standard ASCII: one record per line.
returns are ignored.
tabs are expanded to modules 8 characters.
~ in first column is treated as a EOF.
Binary Card format:
Each record 160 characters.
First characters 6789----
Second character 21012345
111
Top 4 bits of second character are 0.
It is unlikely that any other format could
look like this.
BCD Format:
Each record variable length (80 chars or less).
Record mark has bit 7 set.
Bit 6 is even parity.
Bits 5-0 are character.
CBN Format:
Each record 160 charaters.
First char has bit 7 set. Rest set to 0.
Bit 6 is odd parity.
Bit 5-0 of first character are top 6 bits
of card.
Bit 5-0 of second character are lower 6 bits
of card.
For autodetection of card format, there can be no parity errors.
All undeterminate formats are treated as ASCII.
Auto output format is ASCII if card has only printable characters
or card format binary.
The card module uses up7 to hold a buffer for the card being translated
and the backward translation table. Which is generated from the table.
