I was initially disappointed, but then realized this P21 configuration
did not represent a fast P21 configuration. Didn't Jeff just post an
estimate of 6 mips for the P21 kit configuration, and describe a memory
configuration for 100 mips operation? Would this benchmark run in 2
seconds on that configuration?
I think it would be interesting to have the numbers for the benchmark with
line drawing for 2 reasons:
Forth has faired well in the past against assembly code,
For comparison with the CODEd drawing routines when available.
Anyway, thanks for taking the time to quantify P21 operation.
