Recently I thrifted a copy of Milton Bradley's Electronic Grandmaster.


Yep, that's the one.

The only problem, and since the game is electronic it's a big problem, the game did not come with a cord.


Yep, that's what's missing. I don't have high hopes of finding an original parts replacement, at least not one I'd buy. (My brother says he saw one online somewhere for some crazy inflated price like $100. And yes that was just the cord.) So my next thought was to get something at RadioShack. The wrinkle in that plan is that I don't know any of the specs of the cord. All of the pictures I've seen of the cord just show the top of the transformer, which, aside from letting me know it's a Milton Bradley cord, doesn't tell me squat. The underside of the game itself doesn't give any clues. And the rulebook online (yes, I'm missing that too) wasn't any help either.

So, if you are a lucky owner of one of these big chess machines I would be greatly appreciative if you could share the specs that I assume are on the underside of the transformer. A picture of the underside, or wherever the specs are listed, would be fantastic.

Any other help finding the specs would also be really cool.

The specs from the Manual on page 9 said 115V 60HZ 30WATTS AC ONLY http://www.hasbro.com/common/instruct/Grand-Master_(Electron.... Have you went down directly to RS with it. They should be able to tell by the connection.

Thanks Julie. I've made three trips to my local Radio Shack.

The first trip I just brought pictures which wasn't enough.

The second trip I brought in the game, which was a funny trip because one of the guys there assumed that the game had an internal transformer (due to its size and connector style) so he tripped the circuit breaker when he plugged it in, and they had to reboot their computers. Hopefully this didn't do damage to the game.

The third trip I brought in page 9 that you mentioned, but another guy told me that those specs pretty much just mean that it plugs into a regular outlet. I don't know squat about electronic. But that make sense because looking at a video camera transformer for comparison I see that the input is a range of 100-240 volts while the output is a specific 8.4 volts.

So to be able to find or build a proper cord I need those output specs.

The processor isn't particularly fast. Page 12 of the above mentioned manual says the average time for making a move on level 6 is 1 minute. Level 11 is 3 minutes, 45 seconds. At the top level, 12, the computer will just keep thinking until you push a button to tell it to stop.

I'm no chess master. Back in college I fell for the lose in 3 moves ploy. I was playing a 10 year old. So whatever this electronic game has to offer is sure to be substantial competition.

Personally I'm pretty impressed with what this circa 1982 thing can do...

Well thanks for such a detailed reply.

Honestly I'm not here to defend this machine, though I will say that at the very start of the above video it looks like the game is set to level 1, a level that will avoid winning unless you force it to. As for personal experience with the game, I have none. I haven't even gotten it running yet. That is the goal of this thread.

What did you expect? It's the year 2012, you have a YouBoob video of a chess computer from THIRTY YEARS ago making horrible moves.

I stand by my detailed reply. It was painful to watch...

Wow, that thing is smoking fast compared to my much newer Phantom Force (mechanically, at least).

Really surprised they couldn't help you at Radio Shack. They were able to piece me together a power-chord through simple trial and error (for what little it's worth, 9v 1500mA, tip size M).

I guess if that is your idea of a detailed reply, and it is causing you pain, then it's probably better for you to just drop out of this thread.

For my part, I was amazed. I did not know such things existed, and the idea that it could move the pieces around (even centering the white player pieces) was, well I already said it, amazing. Got me looking into this kind of machine for a future Christmas present. Thank you for sharing.

As to strategy, I'll happily take anybody's opinion that the moves are sub-optimal, but horrible? I don't know, I don't see anybody in check, and while I can see ways to place Black in check in 2 moves, I also see counters so I don't think I'd concede either side quite yet. If it's meant to be a learning tool, and it's set to "easy", then it supposed to make sub-optimal moves isn't it? Your first driving lesson wasn't a manual transmission on the freeway was it?

Lastly, and back to topic, I'd seek a second opinion. Maybe another Radio Shack? There has to be a way to deduce the power requirements, or find them through trial and error without hurting it. Two other ideas, write to MB directly? Long shot, but maybe they kept the specifications? Or keep haunting e-bay and chess sites looking ofr somebody who owns one, just like you're doing here.

Best of luck and I hope you'll come back and tie up this thread when you get your power supply. Meanwhile, thanks again!

Come again? It was totally in jest. Don't be that guy. See the painfully obvious ?

I found this site. They may be able to help if they're still in possession of their copy.

EDIT: Another site you might try.

Mike, just wanted to let you know I ran into the "Phantom" version of this at the Downtown Seattle Goodwill. Unfortunately, it was just the board. No pieces, no box, and no cord. I left it behind.

Did you have any luck getting it to work?

Here's a video of a replay of me beating my MB Phantom version on level 2.

Not sure why the guy posting at the beginning of this thread didn't think a c. 1980s chess computer could make legal moves. Ten years before this machine was produced, the computing power needed to run it wouldn't have fitted inside an average living room. This machine is a marvel and, arguably, a direct descendant of The Turk Automaton Chess Player, from the late 18th century.
