hardware clone: RFT SC2- Intelligent chess

[Steve B]

most often when they say nothing, the east german dedicated chess computers only have an old glass-melting fuse rotten.

exchange the corroded glass-fuse with another and the machines work again.

i think you are correct
both fuses in the SC2 are corroded
i do not want to disturb the fuses in my other SC2 as they are working perfectly
do you know where i can order these fuses?
and do you know the voltage?

ConFUSED Regards

IMO these fuses you can get in almost any electronic shop.

only problem is to find out about the ampere number.

I would ask via telephone (if the shop has those kind of fuses)
and walk with the machine into the shop and ask someone there to
replace the fuses for you without damaging the computer.
also i think that in a computershop someone would be equipped
to help you.

normally these machines come with technical data and an electronic plan
about the components. on this plan there should be the accurate
numbers of the fuses. if you don't have such a plan, there should be those plans somewhere in the internet.

correct again
the Schematic diagram does show the two fuses
one is marked ..T1.6 the other T125

i will try to get them replaced

i wish you good luck. my machine also lost the sound feature. i also think it is the fuse. as far as i can see there are 2 fuses. on for the main power AC/DC, and a second one close to the loudspeaker.

maybe the one at the loudspeaker is off. the wire in the little glass-tube is very thin and one cannot really see very good if it is still working.

after losing the 2 games the machine thought: shit. i will stop beeping

so i will also try to get my second SC2 repaired somehow.

still we have no confirmation IF and WHICH version of fidelity was cloned.

Thanks again for your advice and for your good luck wishes because it worked!
i went to the local Radio Shack and they sold me some 1 Amp ..240 Volt T fuses
4 fuses for $3
i replaced both fuses with the 1A Fuses
the SC2 works and with full sound!

here is a photo quickly taken just now with my Cell Phone:


and here is a game i just played against the PC Engine Pooky 2.7 running under Arena
the SC2 on level 5 loses again(of course)

And just to make sure the SC2 is really working fine i myself played this game against it on level 4(1 minute avg.)

i am very happy to see that your machine is alive again.

[Sylwy]

I wonder if ever, at least in this field, socialists countries produced an original piece of hardware.
AS it is known, the Ural maiframes URSS computers were pathetic copies of IBM 360.
And of course the Ylushin commercial jet was a Boeing 707 badly copied.
etc
etc
etc

What about east germany of those times?

Hi Fernando !

Even the eastern humans are cracked westmen !

Have a nice day !

At least the best two chess engines of our days are mastered by eastern humans:

-Rybka by a Czech
-Naum by a Serbian

Well again i cannot replicate the game
on move 4 the CC10C will play 4.Be3 and not 4.Bb5 as played by your SC2

perhaps it is the longer thinking time..perhaps just random play

i think i am going to give up my short career as a Clone Detective
