[Info-vax] Anyone interested in another public access system

[Carl Friedberg]

Bob,

I'm not trying to start a flame war here. You are being unfair. The fortran
compiler was the RSX compiler with a back-end that generated VAX
instructions, and ran in emulation mode. All of the RSX utilites, and
(especially CVT), the file utilities (VFY, PIP, etc) ran in emulation
mode.

RSX-11 was the basis of the VAX-11/780 design. Even the name
reflects this (Virtual Addressing eXtension -- of the PDP11
architecture).

Just my 2 cents.
