From what I've read, 2.11 is right out except for the little glimmer of hope in the docs that it "would probably only require a moderate amount of squeezing to fit on machines with less memory, but it would also be very unhappy about the prospect," which I think roughly translates to, "don't try it on a puny thing like an 11/34."  

  I wonder if porting telnet and ftp to 2.9 on the 11/34 would be my best hope?  But with a much more antique tcp stack, it sounds daunting.
