  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 agree with Paul.  I've seen dozens of RT-11 systems and non-parity MOS
memory has been more common in the ones I've seen.  I see no reason to
think it would be a problem.  True, 16K is small even for RT-11, but
I've seen plenty like that too.
