A fully-populated 18-bit address space on the /34 and /45 is only 128K words, which seems like a pretty tight fit for a TCP stack with practically sized buffers?
I had always sorta assumed DELUA/DEUNA were only practically useful for TCP on
extended Unibus machines (/70, /44, /24, etc.) but I could certainly be wrong
on that assumption!
