Is Ron Nelson the programmer of this unit? Your post is not clear about this.
And about the strength of state of the art chess computers using 6MHz or slower
processors:
142 Mephisto MM 5 6502 5 MHz 1874 19 -19 1374 47% 1897
144 Mephisto Polgar 6502 5 MHz 1870 16 -17 1813 40% 1938
146 Mephisto Milano 6502 5 MHz 1864 23 -24 900 40% 1936
147 Novag Super Expert C 6502 6 MHz Sel 5 1860 18 -18 1555 46% 1891
149 Mephisto Academy 6502 5 MHz 1839 18 -18 1555 44% 1885
(from the SSDF list)
If this company wants a real good program for their hardware, they should
consider asking Ed Schröder for one of its 6502 programs...
