Hardware Problem
I think my SID chip died \D:/
Yesterday all was working well and then today I wanted to watch Royal Arte on the real thing since I have set up my RR-Net stuff properly a few days ago. Transferred it, loaded, run, no sound. Neither on the TV via antenna cable nor on the stereo via cinch cable.
The only logical conclusion for me is that my SID chip croaked somehow and now I wanted to know if there is a surefire way to tell. Is there som hardware diagnostic tool for the C64 by any chance.
This sucks ass :/

Yago sounds (or no sounds?) like a nice bloke! Ensure your old SID receives a respectful burial... snyft.

hrm, you may not have done bad things, but I have. that said, I go through an average of one sid every 18 months. Arg. |

Ptoing: take a tune and play it, then display the registers on screen. that should tell if something runs through the sid or not.
irq:
;grab sid registers
lda #$34
sta $01
jsr music
ldx #0
l1 lda $d400,x
sta $c000,x
inx
bne l1
lda #$35
sta $01
;play music and display registers
ldx #0
l2 lda $c000,x
sta $d400,x
sta $0400,x
inx
bne l2
sec
rol $d019
rti
btw. dont expect the tune to sound 100% right, as
the sid is now not updated in real time! |

well the sid is already taken out of the socket. When i felt it yesterday while running a tune the thing was hot. And with hot I mean egg-frying-hot, it burned my finger. SO I am pretty sure this SID is off to it's ancestors. |

It's kind of normal that a SID runs hot. I eat each day one fried egg to use the temperature. Mahlzeit! |

My C-64 is dying (old bin and 6581 chip). Anyone know why it has ground hum on a cold-start for about 10 minutes, then it fades away ? The power supply is of the new type, and it works fine on the C-64C (slimline) without the need of a warm-up. Changing SID-chips hasn't fixed it either. Display and everything seems ok.
I have to add: The problem started after I bought the MMC Replay. Does that cartridge consume some extra voltages ?
