16K RAM does not make for much of an RT11 system. The industrial/beefy
11/40's all have parity RAM. My PDP 11/05 has the same core stack as this
11/35.

I should have been more precise, but my point is that this is a
non-parity
RAM basic 11/35 system useful for peripheral
interfacing and
communications. As is, not good for something like RT11.
I wouldn't look at it this way. Non-parity memory is fine for any
application if you judge the risk of memory error to be low enough for that
application. Peripheral interfacing or communications may or may not be
such an application. An application running on RT11 may or may not be.
The OS isn't what decides this, but rather the requirements of the
application: the expected bit error rate for the memory technology in use
vs. the failure rate that's tolerable for the application.
