Plkease remember that the Facit 4070 paper tape punch was bought by
people who tended to Read Th Fine Manual before plugging things in. And
would be tempted to check what PCBs were installed.
I still want to Read The Fine Manual, but I can't remember the last time
anything I bouight came witha Fine Manual. Certianly not anything in the
last 15 years.
