[Simh] VAX-T and PDP-11-T

[Kevin Brunt]

Hi.

I'd like to make one small point about the use of the DN-11 for this.

UNIX V6 and V7 on the PDP-11 supported the DN-11 for UUCP. (UNIX did come from 
a telephone company, after all.) Compared to the existing code base, there is 
relatively little additional work needed to extend the DL-11 support and add a 
DN-11 based outgoing TCP connect operation, and so create a SIMH UUCP 
networking capability.

It would be a shame if the Throttle support conflicted.
