Rebel 10

[Krzysztof Grzelak]

I have a question. Please write how anyone knows if you can install Rebel 10 on Windows 7 64 bit. I know it's a bit older program and it's written on the CD that it's just under Windows 95 and 98. I thank you in advance for all the information

Thank you very much for your help. I have not started anything yet and I do not know how to run it. But thank you anyway.

I do not know how to run it.

Follow the instructions on Ed's page:

"Unzip the 31 Mb archive and start DFEND from the installed ALLREBELS folder."

After you start DFEND, double click the Rebel that you want to run.

Note: Nostalgia is only available if you used these back then.

Note 2: Back then Rebel would take 1 hour to reach Depth 10, and I thought "this must be close to perfection!", these emulated versions reach Depth 10 in 17 seconds, how much would I love to communicate with my past self and claim that I can play near perfect chess in 17 seconds!

Dear Ulysses, the first program I used was Psion: it was so weak that I thought that I played close to perfection!

Is this the same thing that can be played in myabandonware.com? If so, I just played it...

I missed that after 35. fxe4 my queen was left en prise!

I didn't find a resign option, so I continued playing until mate, but pretend I resigned there.

This isn't what I imagined when you claimed it was a weak program! 😵

Dear Uly,

I played against Psion on a PC XT at 8 Mhz... Guess it's probably different on a modern PC.

[Ovyron]

Yeah, I thought about that right after posting my message, how times change and it's actually difficult to emulate some 8 Mhz speed!

This might help you with the DOSBox Dfend emulations at Ed's site:

Emulated CPU Cycles
8088 4.77 MHz = 315
286 12.5 MHz = 2750
386 33 MHz = 7800
486 66 MHz = 26800
Pentium 90 = 69300
Pentium 100 = 77000
Pentium II 300 = 200000

Therefore if you want to play at PC XT 8 Mhz you probably have to set it around 600 cpu cycles to play close to what you had originally.

To select the cpu cycle in Ed's DFend, just right click on a program, then chose EDIT, once you are in EDIT click on CPU under the Hardware heading and then under CPU value emulation speed enter the CPU value you want and then OK, exit and double click on the program again and play it under that speed. If you are not in full screen mode then you should see the cpu value you chose on the header bar of the program you are playing.

You have to do the same for any other program you want to play. And of course some of them might not work at that slow speed.

Anyway if you want nostalgia this is how you set it up in DFend. I had tested and compared the speeds with my old 486-66 and 386-33 computers and the results were pretty close so it works.

ps. under EDIT you can always go back and change the settings to whatever you want. Typically the fastest speeds you obtain by having the setting set at Dynamic and MAX under the cpu cycle. On a good I7 you can probably reach the equivalent speed of a Pentium III 600 MHz around 600,000 or so cpu cycles.

You can test your performance using ED's Rebel 10, 3 test positions and track the improvements in solving those positions with your different cpu cycles settings or max speed settings.

Hope this helps people who have never tried ED's old Dos emulation programs he has at his site.

Regards
Nick

Anyone able to get the MSDOS oldies working? The zip file seems to be missing the Chess.bat file that provides the menu.
