> How is a PDP-11/23 compared to a 486SX/33?

An 11/23 is slower than a 486 if it's running faster than 16mhz. but a
486 is running single user.

> About how many percent is the PDP of the 486?

what is a PDP? choices 1,4,5,6,7,8,9,10,11,11/780,11/750,11/730?

> About how many percent of the 486 is the VAX?

Depending... first I've rarely seen a vax run a single user OS. A
486dx/33 compares to a 3100m38 if they are both running *nix. while the
vax is slower in MIPs it is the ultimate CISC and can do more in fewer
than a 486. It is also optimized for multitasking/timsharing something
the 486 is not.
