I'm afraid that USB driver and protocol is big
enough to eat far more than a
pdp-8 page.
Read my last post from just a minute ago. There is NO NO NO!!!!!
special
software involved on the PDP8 side. It behaves exactly like a console interface.
With the skip instructions, interrupt flag, interrupt enable flip flop and
everything. Only the behaviour of the teletype transmitter flag is slightly
different. But normal software won't detect that (you cannot set the printer
flag if the FIFO is opened and blocked on PC side. That's all).
