Are my eyes deceiving me?  Is someone really claiming that the reason
that computing the Ackerman function in C on a VAX 11/750 takes 3.3
times as long as doing it in assembler on a Z-80A is because a VAX is
just plain slower than a Timex/Sinclair??

Other comments I've gotten by mail indicate that some folks also
question the VAX's "call" & "return" speed compared with a TS-1000.

If a VAX can't do integer arithmetic nearly as fast as a TS-1000, and
a VAX can't do branching nearly as fast as a TS-1000, then why should
one buy a VAX for 1000 times the price of a TS-1000??  (Other than
because you can't get TS-1000's any more  :-)
