     Dead?  Mine run great.
     I just resurrected my PDP-11/05 today.  11/55 last week. 
 Unfortunately, the 11/05 will not ever be able to run my TCP/IP. 
 
    True.  It's a bit, erm, limited.
  However, the 11/55 could possibly stand a chance.
    Huh?  Doesn't RSX11M-Plus require more than 18 bits' worth of RAM, and
 doesn't your IP stack require -Plus? 
  Yes on the second question, and sortof maybe not
on the first one.
 Officially M+ requires 22-bit addressing, but it can be generated for
 18-bit systems. But I have never tried it to see how it fares...

   I've heard reports it tends to leave you a little tight on pool. 
I wouldn't expect pool to be a problem. Pool is really limited by 
totally different parameters, and in fact, I would think that an 11/55 
might have plenty of pool. An 11/24 on the other hand is totally staved 
on pool, even if you have 4M in the machine... (And that is a supported 
machine.) The key is split I/D space.
However, the 11/55 might be short on memory in general... The GEN 
partition might not hold enough to make the system that usable. Lots of 
swapping possibly.
