<p> I've worked on RSTS and RSX both.</p>
<p> WIth RSTS, DEC held you at arm's length - no real
access to internals. If you like what you get, you're OK.
If you want to extend the systems, learn about internals,
add support for strange devices - you're out of luck. It's
a pretty "vanilla" sort of environment.<br>
</p>
<p> WIth RSX, the internals are documented, there's a dozen
ways to access them, and you are pracatically invited to
roll up your sleeves and get to work on the innards.
Strange devices (hardware and "software" devices both) are
welcome. Sources to the Executive come with every system.
Many examples are in MACRO.<br>
</p>
<p> At my RSTS site, it was a good choice (it was used for
Accounting there, so stability and ease of use was
important). My two RSX sites, one had a lot of weird
devices and needed plenty of extensions written to provide
needed support, and the other was an engineering site,
lots of exotic requirements, so RSX was the winner at both
of those places.</p>
<p> And, a purely subjective opinion - RSX is more fun.</p>
