Ugh; that "I" ought to be "|" (and I can see other typo= s), so someone
really needs to proofread those PDF scans if they're going to be regard= ed
as authoritative.=C2=A0 Yes, I can help...

Indeed, when a lot of compilers recognised the Sieve of Eratosthenes being =
used and optimised for it...=C2=A0 Wasn't all that long ago that vehicl= e
manufacturers also started doing the same thing :-)

The WICAT 150 was just a terminal with several serial ports, and was
p*ss-awful (I worked for Lionel Singer, and had to support the poxy
thing); I'm surprised that it beat another box, though...

Yep; extra work for the CPU.=C2=A0 Not much of a benchmark these days, as C= PUs
are really fast; when I was supporting Unify I used to use its automatic tutorial as a benchmark, and I used to joke that I needed a calendar on some boxes...

what they didn't know was that the prominent window was actually an "rlogin" to the Gould that we also sold...=C2=A0 The looks on the= ir faces were
priceless :-)
