Ed,

When I worked with the 6502 processor I hardly did any extensions as
with the slow 4-5 Mhz this was quite dangerous. I tried more extensions
in the Milano program which should have been the main improvement over
the Polgar. It didn't work. 500-600 NPS doesn't justify that.

I didn't know you did those programs.  Amazing what one learns...  I
wrote a 6502 chess program in 1978, and I believe the processor ran at 1
mhz. You must have been working with the hotrod 6502. :)

btw, you might be interested to know that, on my powerbook 5300ce, which
is a ppc 603e running at 117 mhz, Hiarcs 6 (PPC) runs at 328 nps.  This
is an average taken from an epd test suite done for the upcoming KKKup.
This result has been verified on another 5300.  But the point is, it
plays a darned good game nonetheless, and I would venture to say the
extensions are pretty extensive.
