Now that's interesting, and well worth knowing. I've thought about
something like the QED993 in the past, but if it won't run RSTS/E

on any of my PDP-11's. My /73 has SCSI drives in removable trays for
booting RT-11, RSX-11M, RSX-11M+ and RSTS/E.
IIRC, RSTS/E is the one OS I haven't figured out how to install off
of CD-ROM, it can be 'touchy'. As an example, you can install RSTS/E

I didn't recognize the QED993, so I googled it. Found this comment on
the v-c forum...
"The QED 993 is a Xlinix FPGA emulation of a PDP-11. It does not
appear to be fully compatible with a J-11 processor. For example, it
does not appear to have any FP11 instruction support, which is assumed
to be present in a J-11. I haven't been able to get RSTS/E 10.1 or
2.11BSD to run on one I have so for me it is not as interesting as I
had hoped."
I would personally consider a PDP-11 implementation that could not run
2BSD to be seriously broken for my uses (yes I know about 2.9BSD vs
2.11BSD and Split I&D, etc - that's just about picking the correct
PDP-11 type). I surely don't need an uber-fast PDP-11 to run RT-11.
I got along fine with an 11/23 system for professional software dev
for years - as long as the compiles take a handful of minutes or less,
it's fast enough.
I don't have anything faster/newer than an 11/53, but for what I do,
it's enough. Mostly, I run RT-11 and a little 2BSD.

QED993 $175.00
Those are nice, but a lot of us hobbyists are more interested in running
real DEC gear than in replacing a DEC CPU with an aftermarket CPU. from 4mm DAT, but DECnet/E wouldn't install unless
I put it on a
TK-50 first.
