The match against the Saitek Risc 2500 (V 1.04) has been aborted as there were to many losses (overall and:) due to the erratic (or clever?) time consumption of the Saitek. Emulation was very slow too.
As a sparringspartner for the HIGHLY SELECTIVE and INTELLIGENT (it must be, 200-350 NODESPERSECONDINMIDDLEGAMEARETHEPR000F) Stockfish a program from R. Lang was chosen: (Mephisto) Genius 68030 (v. 4.01 in emulation): it had around 30 seconds per move and did his bit of pondering. Intellifish had a small book (12ply, 30kb in size), no endgame-bases but the ponderthing enabled.

Veryvery entertaining games (and understandable by humans (dumb me)); pgn is here:
Also not your typical computerchess with participation of Fritz 5/6/7/8 or other early programs released during the late nineties and advertised with playing strength of 2600 "Elo". I'm in envy of the Brettcomputer owners at that time (I was young and hadn't the money/interest for such things)!
I bought Genius for the iPhone because of these games; the Twerpfish played also always very nice active and strong chess!
In five games the Genius blundered horribly, like here in move 35:

After playing around with fs-UAE and Debian*/NetBSD (looking for precise emulation) within, I decided to stop this experiment alltogether, as it proves basically nothing except that an extremely limited Stockfish plays still very strong chess, because of its very effective search-algos and was written in clean and highly portable code. It doesn't need the million nodes per second to play "shtrong" - it's just the difference between 2600 and 3500 "Elo".
The dedicated chess machines of our time are all to wooden for me to buy one btw. They look baroque and antiquated with their phony golden plaquettes/foil to me (Ach, so schöne handgeschnitzte Figuren aus Echtholz...). Some of them (they've got little computers inside) have to be wired to a thing to become essentially 'wireless' which is madness (or just good business), but have piece recognition and nice blinking LEDs. But electric rays are dangerous for the brain and testicles anyway, so thank you!!!!!
E-boards from DGT are missing LEDs (they're just e-boards) but one can have from them a nice modern/stylish looking
good selling 'Centaur' which is essentially useless (at least for me) as it lacks a long list of features (a pro-/uncrippled version of this thing would be nice). Perhaps in five years...
There are some other manufacturers of solely wooden/plastic but wooden aesthetics devices.
Greetings!
*things were slow there; thougt about dropping a certain dev (who is running m68k ports on real (!) hardware) a mail to give me a benchmark, but this is would've been an idiotic request.
