UNIX(tm) started long before Intel introduced the 8086 chip. 
Searching the WWW tells me that the PDP-11 was a 16-bit machine with 
a flat address space, and so was limited to addressing 64K. The 
original UNIX must have been a lot smaller than UNIX (and Linux) is 
today. UNIX soon graduated to the 32-bit VAXen, and the PDP-ll was 
left in the dust -- an early example in the history of software 

Bob Groves gave us a pointer to ELKS: 
It will run on 16-bit Intel chips like the 8086, but it's a lot 
smaller than Linux. But it could be bigger than the original UNIX if 
it uses Intel's klugey segment-offset addressing instead of flat 
addressing. If so, it's not trivial to say that "ELKS is not Linux." 
And I expect ELKS to have the same problem as real-mode Win3.0: no 

By the way, I too am getting those stupid "failure delivery" 
messages. Only mine also say "This message contains binary or non-
textual data that cannot be previewed within Pegasus Mail" and I 
have to go to "raw view" to read them.
