Eh? What?
There was an option for 8-bit clean communication in the

I am not sure what you mean by '8 bit clean' here.
As far as I know :
Every ASR33 punch and reader are 8-bit clean in that the former wil
lpunch the 8 incoming bits, the latter reds the 8 data tracks on the tape
and sends them unchanged.
I'm pretty sure that's what was meant; the ASR33 will receive and
send 8-bit tape sequences unmolested. Thus "clean", as opposed
to what would happen if it tried to interpret either side as 7-bit
with or without parity.
