- Using the famous BYTE sieve benchmark about 10 years ago, my PDP-11/03
- with hand-coded assembly from the FORTRAN source benchmarked about the
- same as the listed number for an IBM PC (4.77MHz 8088).
-
- A custom-built J-11 CPU ran it in about half a second. My times for the
- various PDP-8s that I've used (in compiled BASIC) have been on the order
- of 750 seconds, but these are estimates because I couldn't declare an
- 8192 entry array on a machine with 4KW fields. The comparable 4MHz Z80 time
- (compiled BASIC) is, I think, about 15 seconds.
