Well, I just had to run it on some older hardware...
12MHz 80286 running MINIX 1.6.25 and the classic C version of dc:
real 4.00
user 3.56
sys 0.25
DEC MicroPDP-11/23 running PWB UNIX 1.0 and the assembly coded dc:
real 29.0
user 22.2
sys 0.7
Watching the prime number generator (from the Wikipedia page on dc)
running on the 11/23 is much more entertaining than doing it on the
modern workstation I'm typing this on:
2p3p[dl!d2+s!%0=@l!l^!<#]s#[s/0ds^]s@[p]s&[ddvs^3s!l#x0<&2+l.x]ds.x
Incidentally, the Wikipedia page only lists Robert Morris as author of
dc. If anyone here is able to edit Wikipedia, now would be a good time
to get Lorinda Cherry's name on there, too.
