Well I could buy a used serial punch for about $800 to $1000 us
but they are not for a song like many people have picked up 8's
with a tty or high speed punch. The lack of a punch has kept me from
doing a PDP/8 in a CPLD as well as not knowing of where to get
ferromagnetic? ram. I want real non-voiltile memory.

Keeping dry is the hard part unless you got a water tight storage for tape.
Accidents with water like a broken water line, flood or heavry rain just
wait to happen.
