What was the proportion of readers that read
colum-serial versus row-
serial? I believe the CDC 415 punch had its read station as 80
brushes, reading the card just punched row-wise.
It is it character based device or a record device?
026, 029, etc. would obviously read a column at a time (12 brushes).
084, etc. would read a row at a time, even though they were only
reading one column (one brush).
But, if there would be no processing of the data until it was all read,
obviously 80 brushes and a short path would be faster than 12 brushes and
a long path.
