[Braillenote] PK keyboard

[beth]

Hi, all.  There was a very small manual Braille writer which used adding
machine type tape, on a roll, inserted into the writer, cannot recall its
name.  Don't get excited, it was famous for jamming and the tape would come
out on the left side of the unit with each keystroke and you would get quite
a mess after a while!  I'm assuming it's about the same size as the PK.
Does anyone with a PK recall that Brailler and are the keys on the PK about
the same size?  Thanks.  Beth
