that drove them across the hammer bank.
These are the type slugs of the print train
used in the IBM 1403-N1 printer.
Each had 3 embossed characters, behind which were 6 teeth that engaged with
a drive gear on the right hand side and an idler on the left.
Behind the embossed character flange was another plain flange, the two of them straddled a rail,
hence the name print train.
There were 80 type slugs. This was the fastest line printer, capable of 1100 lines per minute.
That is 2.2 lines per second, and on each line could be 132 characters,
which means just over 290 hammer blows per second.
