Old fucked up c64 models
Anyone experienced games that would not run or crash for no reason on your C64 ?
I have two commodore 64 1984 models, and they both
crash on my disk version of Myth Cartridge.
Recently I got this game tested on someone else's C64
equipment with a oceanic disk drive and the game was running without any problem (both pal and ntsc).
So, I put up my c128d and tested the game there, and,
yes! it was running without any problem from my 1581 and 1571 drive. Tried running the game again on my two c64, and - yes IT WAS CRASHING again.
All my other games are running nicely on these 2 c64, so what is the problem ? I have heard about demos that wouldnt run because of the chips was too hot... So i let
the c64 heat for a few hours, and then tested the game,
crash! still no luck..
Now, I talked to Bamboo on IRC the other day and he
said he experienced similar problems on the game HOOK.
He said something about the scrolling routine would
crash the machine. And he got a 1982 UK model.
AFAIK Myth uses dd04/dd05 to do the scrolling.
We sort of came to a conclusion that certain old c64 models
would fuck up..
Well, any comments.. anyone ?

No, running with a REU PSU is a good thing even if you don't use the REU. I guess they ment you should use a newer model PSU instead of the old, brown one. They tend to fuck up alot. A REU PSU is as reliable as a C128 PSU.

Overheating of chips in the computer often result in these type of strange behaviour ( like some of you already mentioned ).
If you want to examine a "semi-working" c64 for overheating problems, buy some "cooler-spray" from your local electronic component shop. Here in sweden it can be bought at elfa and biltema. Biltema charges less that 30SEK for a bottle if i recall it right.
By spraying one chip at a time you can conclude which chip it is that starts to fail when reaching working-temperature.
Another tip is to mount transistor radiators ontop of the most often failing chips. I've done that on my SID, VIC-II, CIA's, PLA, ROMS, CPU.
Cooling the chips extends MTBF a LOT!
This must be done BEFORE your chips start to fail!
Anyone intressted in getting some instructions about cooling those vital chips inside your C= hardware? ( if enough people want this I might write a HOWTO about it )
