Well, the HTTP protocol is almost more or less just a glorified cat...
There isn't that much to it, really.
HTTP is more like CRUD (create, read, update, delete) than cat.

Well, I'd used the word Weakest to describe this aspect of a computer...
Without reading any PDP-11 architecture handbook (today), I'd like to
claim the initial design, the 11/20, to have the weakest architecture

Just as all (almost) PDP:s
I would have to concur. I have a physical 11/05. The 11/05 (same CPU as
the 11/10) and it is nowhere near as capable as an 11/03. For a while
there DEC had a tendency to release two new machines at a time. One
would out perform the previous flagship processor, probably not costing
too much
I should point out that the LSI-11 does not have EIS in the basic CPU.
It's an option you can add, which have both EIS and FIS (the KEV-11,
horrible :-) ).
The LSI-11 is also 16-bit addresses only.
I tried finding any information about the speed of the thing, but
failed. But I think it is

In terms of sweet and small, you want Alan Baldwin's TCP/IP for RT-11
implementation. http://shop-pdp.kent.edu/
It has a very nice and sensible TCP/IP application interface and in fact comes
with a webserver and other common TCP/IP applications and utilities.
