Subject: Upgrade Mephisto Exclusive to Genius 2.0 68030 Modules

Author: Mark Gaddis

This message may be somewhat lengthy. Please bear with me.  I was really into
computer chess in the early to mid 1980's.  Then I got a new job, got busy with
other things and dropped out of the computer chess world for the last 12 year.
Now I'm back and I have a lot of questions.



First, In 1985, I bought a Mephisto Exclusive chess computer from ICD with the
Amsterdam Module.  At the time, it was touted as being master strength.
Hindsight has shown it was not quite there.  I am attempting to upgrade my board
to be able to run the Genius 2.0 modules.  The Amsterdam module is a 68000/12MHz
machine.  The Genius 2.0 is a 68030/33MHz machine.  Can anyone give me the
specifics of doing this upgrade.  As you probably know, the Mephisto company is
defunct.  I have talked with Bob Marzano who used to do this upgrade for Steve
at ICD and he said that faster octal latches need to be installed on the
interface board.  He couldn't remember the specific part numbers.  Does anyone
know what chips need to be installed?  Also, I don't know what the power supply
requirements are, ie voltage, current etc.



I am also looking for a users manual for these modules.  I am an electrical
engineer, so I think I can do the mods if given sufficient information.  I would
greatly appreciate any help that you can give me in this endeavor.
