summer tournament

i am doing a little summer tournament at 40/120 with some older dedicated chess computers and also homecomputer software.

i did some games and have played out 4 rounds but now took some more participants in.

the idea is to have as many different programmers beeing into the tournament to have a big variety of playing styles and behaviour present.

The TASC FCC (sold 1989) was an extension module for the C64 with an external 6502 with 5 mhz inside.
The engine by Marc Derksen used the (home)computer (c64 or PC)  for the graphical Input/output.
A marvellous chessboard, pull down menues in SAA standard and almost all features you could imagine.

Colossus Chess 4 (from 1986) by Martin Bryant runs on the C64. Normally the runs only with 1 mhz, so i overclocked the machine to 5 mhz to give colossus a better hardware platform for the games.

I am using a special motherboard for the C64 that runs on a FPGA that allows all kind of mhz up to 48.
Depending on the way the programmers created the clocks in their programs the clocks run in normal speed so i can use normal time controls.

For the time made martin bryants prg was also state of the art showing NPS, evals, depth and main line, branch computed and move list.

I wonder why colossus never came into a commercial dedicated chess computer. As far as i know it was „only“ sold as software for several computers.

The TASC FCC runs in an emulation.

The FCC mated Colossus Chess 4:

Man muss sehen das damals, 1985 der Frans noch etwas stärker war als der Ed auf dieser Hardware.

In 1985 sah die Amateurgruppe der WM in Amsterdam so aus:

Its always astonishing to see how Frans Morsch was capable to generate search depth with low hardware Power.

The Mondial II runs with 2 mhz only and has only 2 KB RAM.
Nevertheless it comes most often each computation 7 searches deep.
In the endgame even 9.

Superconny was not capable to create a wonder. The opening was blocked and although superconny tried f5 it did not made it.

I believe the answers are:

1. still using assembly language long after "sensible" people moved to high-level languages

2. Vincent told me that Franz had boasted to him that he was able to evaluate positions in something like 50 instructions. This is nowhere near enough to evaluate a chess position, so what I think he must have been doing is just amending the previous evaluation in the next ply of the search. This would obviously not be 100% watertight, but apparently worked well in the era of 6502-style CPUs

Frans was a master of memory usage and efficiency.
Its very obvious that he maybe used pre processing.
Evaluate the position FULL before the search and only evaluate in the tree the changes .

E.g. tree move brings bishop from f1 to c4 and gets a bonus because on c4 the bishop is developed while on f1 it was not.
So add bonus to the pre processed evaluation.

Later (after 8 bit era) frans combined this strategy with null move.

Of course we only guess because we cannot look inside and see only what the machine outputs to us.

In the next game the TASC Final Chess machine with 5 mhz can rescue itself against the Chafitz Steinitz encore 4 mhz with Queens check into a draw.

The final chess card runs an engine by Mark Derksen who was a TASC worker at that time in charge for the well made GUIs of the TASC products.

The Chafitz Steinitz encore has an engine by Larry Atkin.

The game was kind of strange because the final chess card evaluated its position until 32th move positive with score from 0.3, 0.9 until 2.2. This completely changes on c7 and it said within a ply -1 and later more.


the final chess card also reaches search 7.

it first looked like a win by colossus chess, but then the Chafitz Steinitz encore Master tourned the game.

Interesting what Larry Atkins program makes out of 4 mhz.

As you can see from the data, Superstar36K and Tiger Grenadier will have to play today. Not against each other because they played before (Tiger won) but against others.

Seems that this opening was only suboptimal for black.

white has no problems to begin an attack.
