Bought and disassembled a commodore c64 Empty
PostSubject: Bought and disassembled a commodore c64   Bought and disassembled a commodore c64 EmptyMon Mar 29, 2021 2:12 am

I bought and assembled a ryzen 9 3950x.
Nobody here reacted.

As a result i now bought a commodore c64 with 1 mhz clock speed.
I cleaned and disassembled it and will soon upgrade it.

Today my PCB from netherlands came. I put the old pcb away and put the new one in.

Now i can run the c64 instead of 1 mhz with 48 mhz without timing issues.

So i can run any c64 chess engine with factor 48 onto my flat screen in the living room.Modern C64 PCB

C64 ultimate elite

I begin with putting the c64 from 1 to 4 mhz.
Then i take out my monte carlo IV with ed schröder software and let colossus fight 4 mhz versus eds monte carlo IV engine.

Bought and disassembled a commodore c64 189c2d10


Both engines now use 4 mhz 6502 environment.

Monte Carlo IV came out 1989

Colossus 4.0 is from 1985.

the first game between the two opponents was a tough game and they were both very close concerning playing strength in it. see yourself:

This is astonishing if we think about that colossus was sold 1985 while Eds maschine came out 1989.

I wonder why Martin never ended in a dedicated chess computer :-)

Maybe nobody remembered how strong those old homecomputer software engines were. Or people used the buggy atari st/amiga/PC Version Colossus X as a reference.

the next engine i tried on my slightly oc C64 hardware is Chessmaster 2100.
Chessmaster 2000 had a Kittinger engine.
But this Chessmaster 2100 is different. It has a Spracklen engine.

Here the game against Monte Carlo IV:

We don't know exactly which engine they used in the CM2100.
And with 1 mhz it would not have had a chance against the Monte Carlo IV.

After 1988 not many people tested the engines on the C64 mainly because with 1 mhz they had not much chance against the faster dedicated chess computers on the market.
and then came the 16 bit hardware and the c64 was an old fossile.

but we have the chance today to find out how these engines could have played with SIMILAR hardware and relate it against each other.

Novags Super-Forte C has a Kittinger Engine.
It is together with Ed Schroeders Engines on 6502 a very strong opponent for the engines on C64.

the next opponent is a fidelity elegance, a tiny wooden machine from USA with spacklen program. it is tuned to 8 mhz so the hardware of both machines is

The c64 is back, operation system has been "enhanced":




SAA standard pull down menues on the 1 MHz C64 !!

Looks like windows. Even better look like any Fritz GUI from CB.


C64 OS

This is probably the smallest GUI OS there is. Two years ago, this article (link) said that the smallest GUI OS fits on a floppy disc - but 1.44 mb (floppy disc capacity) is FAR too big for a C64.
