The RISC 2500 lives!
Sincere thanks to Steve and Larry for guiding me through this.
The voltage converter, purchased for 40 smackers at Radio Shack, functioned perfectly. This RISC contains version 1.04, with the 2mb upgrade.
The lights went on in coruscating order, as Larry described. I played a test game. RISC answered my 1. e4 with a Pirc. I tried the Austrian Attack. After about 15 moves, the RISC tore my arm off and clubbed me with it.
The trick was how to introduce this monster to its playmates. I needed a strong opponent - not the top of the existing line, not yet - but something strong. Something smug. A board with an oversized ego. Citrine.
Here's the result. Citrine agreed to play Black. Both machines set at default levels. The referee was drunk.
[Event "Tabletop follies"]
[Site "Chez Reinfeld "]
[Date "2012.04.26"]
[Round "1"]
[White "RISC 2500"]
[Black "Citrine"]
[ECO "E10"]
[Result "1-0"]
1.d4 Nf6 2.Nf3 e6 3.c4 d6
On the third move, Citrine shuns RISC's invitation to the Nimzo-Indian, and plays a curious, cramped little move that blocks both of his bishops. We are out of the books.
[fen]rnbqkb1r/ppp2ppp/3ppn2/8/2PP4/5N2/PP2PPPP/RNBQKB1R w KQkq - 0 4[/fen]
4.Nc3 Be7 5.e4
RISC accepts the offer to build a big center, free of harassment. It's always been curious to me that computers, left to their own devices when out of the books, decline most opportunities for fianchettoes. I suspect a capable chess programmer could explain this tendency.
O-O 6.Bd3 Nc6 7.O-O Bd7
Black leaves a little opening that invites harassment.
8.Qb3 Rb8 9.Bd2
It's hardly decisive, but White has the freer game and his rooks are connected.
9...Be8
The beginning of a bad idea: Citrine wants his KN and KB to trade places so he can put pressure on d4 and undermine that big center. He loses time in cramped quarters. It's easier for RISC to shuck and jive through here.

10.Rac1 a6 11.Ne2 Nd7 12.Be3 Bf6
Citrine gets what it wants, but RISC has three defenders guarding d4, and a fourth to come.

Stupid. Computers are stupid.

[fen]1r1qbr1k/1ppn1ppp/p1nppb2/3P4/2P1P3/1Q1BBN2/PP2NPPP/2RR2K1 b - - 0 14[/fen]
Dull-witted Citrine discovers a new way to disarm itself, and prepares to trade a good knight for a crap bishop.
14...Nce5 15.Nxe5 Nxe5
[fen]1r1qbr1k/1pp2ppp/p2ppb2/3Pn3/2P1P3/1Q1BB3/PP2NPPP/2RR2K1 w - - 0 16[/fen]
Right here, RISC 2500 fired a cute little shot.
16.Ba7 Nxd3 17.Rxd3 exd5 18.exd5
[fen]1r1qbr1k/Bpp2ppp/p2p1b2/3P4/2P5/1Q1R4/PP2NPPP/2R3K1 b - - 0 18[/fen]
At this point, the rook's got to move; RISC starts carpet-bombing the queen side and gradually forces a win of the exchange.
18...Ra8 19.Qxb7 Bxb2 20.Rb1 Be5 21.f4 Bf6 22.Bb8
[fen]rB1qbr1k/1Qp2ppp/p2p1b2/3P4/2P2P2/3R4/P3N1PP/1R4K1 b - - 2 22[/fen]
The obvious threat is 23. Qxa8. The only good answer (found by software) is 23...Ba4! Citrine misses it, and RISC grinds down.
23...Rxb8 23.Qxb8 Qe7
Exchanging Queens here is a terrible option. Citrine wants to get his bishop out. RISC plays along and allows more liquidation.
24.Ng3 Bb5 25.Nf5 Rxb8 26.Nxe7 Bxe7
And Citrine comes out on the short end again...
27.a4 Bf6 28.cxb5 h6 29.a5 axb5 30.Rdb3 Bd4+
Spite check. From here, it's over.

This is going to work out expensive for poor Reinfeld, I'll tell you why:Steve B wrote:

In recent times the Australian dollar has appreciated heavily versus
the US dollar. The exchange rate is $1Aus = $3US, therefore....
$50 X 3 = $150 regards...

Payments will be forthcoming, along with a souvenir Euro to US adapter that I don't need...barely used!
Adapting regards,

I find it amazing that the above link to a not very interesting photo of my Saitek Adapter is getting some of the highest view totals out of all of my over 1500 photos!Steve B wrote:Well i can answer a few of your questions
here is a photo of my Saitek 2500(2MB) power supply
http://www.flickr.com/photos/10261668@N ... hotostream
On a good day i get anywhere between 75-125 views on my collection site..some days spike to 300-400 views..some days crater to 25-50 views
a typical photo has received about 75-100 total lifetime views
total views to date are about 130,000 in the 7 years since i opened the site
this is of course nothing compared to other Internet photos and videos which can go viral and get 3-4 million hits within days
usually these viral photo's/videos are about very interesting world shattering topics like someones pet pooping in the back seat of a car or of someones 2 month old baby upchucking his breakfast on his bib
but i simply do not understand why an adaptor would get over 75 views in 2 weeks??
now can i ask ..
What Is That Exactly Regards?

Saitek Risc 2500
Can someone please help me upgrade my Risc 2500 to 2mb? I recently bought one with the onboard 128 kb from a collector friend in the Netherlands and want to have it reach its full potential. What do I need to buy? What stores in the US sell them? I will also need instructions on how to install when I receive them. Please help.
Best regards,
CCWB

along to an electronic parts supplier. If they don't have any suitable
RAM, which they probably will not, they will more than likely be able to
refer you to the right place.
Check this one out:http://www.meca-web.es/articulos/memoryup.htm
A nice link to read:http://www.spacious-mind.com/html/risc_2500_2mb.html
get back to us and let us know how it's going,
all the best...

I finally had my Saitek Risc 2500 upgraded to 2mb of RAM. I found a seller in eBay located in China that sells what I needed. I have some disappointment though in the way the Risc 2500 performs against the Berlin 68. . The Risc2500 has higher elo rating than the Berlin 68000, but the latter has more wins than the former in 30-minute games. It's like 3-1, or 3-2 in score for the Berlin. I have not tried to match them in long games. Is the Risc 2500 going to be stronger than the Berlin 68000 in long games? Has anybody tried it?
Thanks in advance for the info.

The Wiki clearly shows the Risc 2500 Stronger then the Berlin 68k across all time controls ..including 30 sec per move (Active rating)

my guess is you need to play more games for the results to turn around
Risc 2500 > Berlin 68k Regards
