For short tapes, running it through a rotary paper cutter rig would let you
cut it down to the right width. Problem is you could not use anything but a
custom built or modified reader. Leaving the MSB 0 would get you accurate 7
bit bytes/words with 8 bit byte alignment for simplified reading and

M-W says "to make lustrous" and "to give a new look to."
"Refurbish" is "to brighten or freshen up."
At Dell Outlet, for example, I think they call a computer "refurbished" even
if it never left the warehouse -
I can punch arbitrary 8 bit data to 8 level tape. Is the MSB always 0? That
is very easy to do, just make sure the binary looks right and as long as
the pitch between bits is the same as 8 level tape you will end up with
holes in the places you would expect.

For HDDs, "refurbished" probably means FORMAT'ed.
In the old days, it sometimes meant a LOW-level format.

For other things, it probably means plug it in and see if the power
