hardware clone: RFT SC2- Intelligent chess

Post by mclane » Tue Mar 31, 2009 8:28 pm

one dedicated chess computer was illegally cloned by eastern germany (GDR) and sold into the world.

With components from eastern germany they copied the Fidelity Chess Challenger 10 (we don't know which version) and made a kind of remake of Ron Nelsons Fidelity machine.

They even copied the flickering of the oooo display between odd and even plies.

my version had a slightly different box, where the red picture with the young
girl playing chess is put above the original green box picture.

here how my box looks:

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?

i can replay it in a day or so
what level was the SC2 on?

one thing i notice immediately is that the SC2 castled at move 16
the CC10(version a) never castled
this was corrected in the CC10b version
so i will use the CC10b

i think it was level 6.

the good thing with the SC2 is IMO the keys. they are very easy to press. more like the keys of a typewriter.

much better than he sensor keys of the original fidelity machine.

btw. the SC2 beeps in a cyclic number of time, similar to the "your move" of my voice. one can turn off this beeping when it is the opponent to move.

is the version 10 also having this kind of beep ? or is the SC2 maybe a voice with a beep instead of the voice ?

i can do another game (revenge) at the week end.

i wonder why the GDR version has green LEDs.
green LEDs versus red LEDs.


BTW: i read in a german forum that 2 versions of the SC2 exists. they can be identified by the production number:

G-5002.500 2.5 mhz
G-5002.501 4 mhz

i think i do have the 2.5 mhz version.

not sure of the Question
the CC10 does have a beep which can be turned on /off

when it is the opponents time, SC2 beeps after a few seconds or minutes.

this is IMO similar in the VOICE, the fidelity voice repeats after a while that you should move, that it is YOUR TURN to move. i do not exactly remember what my fidelity voice says, but it makes a comment after a while. instead of talking the SC2 beeps.

i wonder if the Fidelity 10 do also beep after a while when they are awaiting opponents move .

of course the machines have a normal beep that happens when you press a key or when the machine moves.
i am referring to the beep that comes when you do nothing.

ok now i understand

the CC10 does not send a warning beep for the player to move
also..there is a problem with the playing levels
Both of my SC2's show level 6 to be 4 minutes and 50 seconds avg time per move
there is no equivalent level for the CC10
the two closest level's for the CC10 would be level 9..which is 6 minutes per move or level 10 which is 3 minutes per move?
