They were 5 6 7 and 8 level models. I need to dig around for an 8-level manual
for bitsavers
since it appears the parts data in the book that I have only covers 5-7 level.
BRPEs were used as the paper tape punch in the PDP-1
Later DEC machines used Litton punch mechanisms

If somebody found a mains cord that "fits" and plugged it in with the
low voltage AC input connected to the wall, then it might not be happy now.
You might want to avail yourself of some of Allison's expertise.

Along these lines, it's been a long time since we've updated the list
regarding the QSIC
Again.. I really think you are overthinking this.
MCU should set receive line coding to 8,N,1. When in command mode, you
don't care about parity as it is presumed the connection from the host
machine to the modem is short and largely has integrity. Every byte you
receive in 8,N,1 command
This is interesting indeed. But if someone wanted to emulate a new function
with the QSIC, would they need to be able to program in verilog (or fpga
language)? I think an interesting angle using something like a BBB is that
there is probably a range of languages that could be used to implement
