[GreenKeys] BRPE11

[Nick England]

According to the 1969 catalog, BRPE11 + BRPEB6 is
6 , 7 , or 8-level, 7/8" or 1" width, In-line feed hole
633 wpm
28VDC 1 ampere signal and tape feed out magnets
See pdf page 10

I thought that the parts book showed that the adjustable punch block would
handle 5-8 level?

I really need to get back to my BRPE project - I got a couple of the
typesetter 6-level units (with leading feed hole) and convinced some
machinist buddies that making a new 5-level in-line punch block would be a
"challenge". Now I need to build some driver electronics and figure out how
to feed it a character stream.
