My understanding is that the Micro PDP-11 (ie 11/23, as opposed to the 
Micro PDP-11/73) has full memory management, except I&D addressing.

I posted something to this effect a couple of weeks ago, but the link was 
a bit iffy around then, and I suspect it didn't get out of NZ.

Basicly - I also have a Micro PDP-11, sans (useful) OS.  I would *love* 
to hear about a Unix, or any other timesharing OS for the beast, which 
isn't going to cost more than the machine did (like the systems DEC would 
love to sell me, ie RSX or RSTS).  

The spex are:  Micro PDP-11 (11/23), 512KB main memory, RD52 hard drive 
(30MB), RX50 floppy drives.  I really need something bootable.  I can 
convert 9track magtape to RX50 via a VAX, given instructions.

Love to hear from anyone willing to help.
