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 ?

I have noticed similar crashes in MAYHEM IN MONSTERLAND and CREATURES, presumably due to the same thing.

yes, it's due to the same thing.

There is a solution though. Get a different c64.

There's also a different ROM in some really old C64 (check AAY64). I have one and RED STORM/TRIAD isn't running on it but on my other (&newer) C64/C128 it works just fine. The AGSP-bug seems to have something to do with warm ICs (my C128 really hates these effects when it's running for some minutes... :(

@wvl:

well i have lots of 64's here & my main machine is a 128D.
Never had this prob on any of them but i know ppl
who have them all the time, doesnt matter if the
machine is cold or hot.

@ Raven : I have one machine that has the bugs when it is hot. I can run f.e. Insomnia on it the first time when I turn it on, If I try again it will almost 100% crash. Same for other demos (especially Dutch Breeze)... it really matters if the machine is cold or hot.

my first c64 behaved pretty strange, it crashed for example always on IK+, but had no problems with dutch breeze.. :)
