Thanks to everyone who has sent suggestions about remote job submission
from a simulated PDP-11 to a simulated IBM/370.
Although I do want to get this working on a simulated PDP-11 running
RSX-11M, the mention of the Unix 'send' command grabbed my attention, since
that rings a vague bell in my

Indeed. I brought up real hardware because that is the foundation of
my knowledge of RJE but I wasn't intending to propose that as a
solution.

Good to know about both of those chips. I
Well, the solution is simple: Build a UNibus to USB interface so SIMH
can use the physical devices properly. That can't be too hard...

Interesting. I think these came from that E-COM US Postal Service thing
in the late 1980's where the USPS built a pilot system to allow you to
go into a post office, give them a letter, then they would scan the
letter, route it through a network of pdp11's to the destination PO

Similar in principle, not in implementation.

Big big boards with a bunch of Z80's on them to do all the protocol
