Glad you enjoyed the post as well Terry
as for the game..
i realize i am playing against very weak computers and i am playing to their weaknesses (small ply searches etc) so i dont show the games to indicate any level of strength on my part
i only try to show how the computer plays and that it still does work

Ed Schroder was well know for his Mephisto programs running on the 8 bit 6502 processor..Indeed many collectors today consider Schroder to be the Premiere 8 bit chess programmer of all time

Schroder was also one of the very first programmers to program for the Risc Processor

even to this day, his Risc I-1MB ( 2232 Elo) and Risc II-1MB ( 2261 Elo) are considered highly desirable additions to any collection
they are also very delicate finicky computers with a very high defect rate
in fact i had a Risc II go belly up on me a few years ago but luckily Ruud Martin (of Resurrection fame) was able to repair it

the power requirements for the Risc I and II call for a rather unusual 5 Volt adaptor (off hand i cannot think of any other computer that uses this voltage)
other then the start up screens the Risc's can be differentiated by the program modules casings which are some what different

Risc I:

Risc II:

http://www.flickr.com/photos/10261668@N ... 922171154/

it should be pointed out that i know of collectors who have the module casings reversed but i am fairly certain these are the original program casings for the programs

feeling a bit playful i wanted to experiment a bit and have some fun.

Veeery carefully and tenderly ..i set up the fragile Risc II and i took the white pieces playing at the normal start up level (10 sec.avg per move)
the game proceeded thusly:

[White "Steve B"]
[Black "Mephisto Risc II"]
[Level 10 sec.avg.per move]

1. d4 c6 2. c4 d5 3. Nf3 Nf6 4. e3 e6 5. Nc3 Nbd7 6. Bd3 dxc4 7. Bxc4 b5
8. Bd3 a6 9. O-O c5 10. Re1 Bb7 11. Bd2 c4 12. Bc2 b4 13. Ne2 Bd6 14. Ng3 O-O 15. Qe2 Rc8 16. e4 c3 17. bxc3 bxc3 18. Bg5 Be7 19. Qd3

the Critical position
[fen]2rq1rk1/1b1nbppp/p3pn2/6B1/3PP3/2pQ1NN1/P1B2PPP/R3R1K1 w - - 0 22[/fen]

on the 10 sec level Risc II proceeded with:
19.h6 and there followed:
20. Bxf6 Bxf6 21. e5 g6

[fen]2rq1rk1/1b1n1p2/p3pbpp/4P3/3P4/2pQ1NN1/P1B2PPP/R3R1K1 w - - 0 22[/fen]

not satisfied to end hostilities in this quick manner(up a piece for a pawn and with a strong King Side attack.. to boot) i then reset the position
back to the critical position and bumped up the level to tournament
strength-40/2hrs

from the critical position play then followed:
19..g6
20. Bh6 Re8 21. e5 Nd5 22. a3 Qa5 23. Nh5 Bxa3 24. Qe4 Rc7 25. Qg4 Nb4 26. Bxg6
hxg6 27. Nh4 Kh7 28. Qg5 c2 29. Bg7 c1=Q

[fen]4r3/1brn1pBk/p3p1p1/q3P1QN/1n1P3N/b7/5PPP/R1q1R1K1 w - - 0 22[/fen]
Risc II was very very pleased with its performance at this point and had me
down -3.65
that is until i unwittingly stumbled upon the eye gouging ..10 volt powerhouse..
30. f4!!

[fen]4r3/1brn1pBk/p3p1p1/q3P1QN/1n1P1P1N/b7/6PP/R1q1R1K1 w - - 0 22[/fen]
at this point the evaluation took a nose dive from +9.99 to -9.99
the game continued with..
Qxe1+ 31. Rxe1 Kg8
speaking directly to the 5 volt adaptor i was more then happy to announce a Mate in 5
32. Qh6 f5 33. Bf6 Re7 34. Qh8+ Kf7 35. Qg7+ Ke8 36. Qxe7# 1-0

Risc 2500/Montreux also need 5V

IIRC all these computers/modules don't have a voltage regulator built in, so a common 9V adaptor delivers too much...

all the best,

I've suspected Steve of being a very strong player for quite some time.

Fritz 8 gives me LOADS of trouble!

Hi Mikey

to prove i am no Anand i offer this game i played against the Mephisto Phantom Robot which was due for its annual workout..

the Mephisto Phantom is the same Exact Computer as the
Fidelity 6100 Phantom but it was released by Mephisto after they bought out Fidelity

it contains the famous Par Program programmed by the still ..after all of these years ..happily married.. husband and wife programming team of Dan and Kathy Spracklen
it was rated about 1834 ELO(SS)

the Mephisto Phantom:

the time control was Game\30 Minutes and the game itself was not particularly noteworthy ,featuring the normal course of events in which i am down about 2-3 pawns with the endgame looming ominously ahead

however,just as all hope was lost , i stumbled upon a "Reshevsky" like swindle..and i nailed down a draw by perpetual..

[White "Steve B"]
[Black "Mephisto Phantom"]
[Time-Control Game 30 min]

1.d4 d5 2.c4 e6 3.Nf3 Nf6 4.e3 Nc6 5.Nc3 Be7 6.Bd3 O-O 7.O-O Nb4 8.cxd5 exd5 9.a3 Nxd3 10.Qxd3 a5 11.Re1 Bg4 12.e4 dxe4 13.Nxe4 Bxf3 14.Qxf3 Qxd4 15.Nxf6+ Qxf6 16.Qxb7 Bd6 17.Be3 Be5 18.Rac1 Rfb8 19.Qd5 Qd6 20.Qxd6 cxd6 21.Rc7 Bxb2 22.a4 Rb4 23.Bd2 Rxa4 24.g3 Bd4 25.Ree7 Ra1+ 26.Kg2 Ra2 27.Bf4 Bxf2 28.Kh3 Bb6 29.Rb7 Bd4 30.Bxd6 f5 31.Red7 a4 32.Bb4 Bf6 33.Rd5 g6 34.Rdd7 g5

[fen]r5k1/1R1R3p/5b2/5pp1/pB6/6PK/r6P/8 w - - 0 35[/fen]
here the Phantom ..up two pawns and with a passed Rook Pawn ..is threatening mate on the next move with g4
I dont think so.. i limp on ..

35.g4 fxg4+ 36.Kxg4 Rxh2
37.Bd6 h5+ 38.Kf5 Rf2+ 39.Kg6 h4???

[fen]r5k1/1R1R4/3B1bK1/6p1/p6p/8/5r2/8 w - - 0 40[/fen]

here is where i struck lucky
the Phantom at this point thought it was ahead +3.34 but when i moved my King
to G6 i already had this in mind..
40.Rg7+!!
[fen]r5k1/1R4R1/3B1bK1/6p1/p6p/8/5r2/8 w - - 0 40[/fen]
Sammy himself would be proud of the swindle sacrificing the Exchange to force a 3 Fold Repetition
the Phantoms PV evaluation plummeted all the way down to ..+0.00

40.. Bxg7 41.Rxg7+ Kh8 42.Rh7+ Kg8 43.Rg7+ Kh8 44.Rh7+
Kg8 45.Rg7+ 1/2-1/2

FINAL POSITION

[fen]r5k1/6R1/3B2K1/6p1/p6p/8/5r2/8 w - - 0 45[/fen]

Death Be Not Proud Regards
Steve

the auction ends at over $800!
for the modules alone with NO BOARD
it is not even the Mephisto RiscII-1MB

PS..i wonder why the seller is including a copy of the Genius instruction manual which has nothing to do with the Risc?

Hi Steve

Steve B wrote: PS..i wonder why the seller is including a copy of the Genius instruction manual which has nothing to do with the Risc?

He wrote: As the modules were in a Genius 68030 box, he first thought, they were Genius modules.

So one could better ask: Why is he including the Risc 1 MB manual, if he thought, they were Genius modules?

risky regards,
Robert
