Buying Commodore ICs from China
Hello all,
just posting a story about buying Commodore ICs from Chinese suppliers. Before buying read this.
Interestingly there are suppliers that in 2006 produced fake Commodore ICs.

The attached .jpg (in weirdly large size) approves that you did everything right. I would suspect the chip to be malfunctioning :P. Was i funny now? :D |

Crap!! Sorry for the big pics, I was too tired last night and too in a hurry for uploding the pics for noticing the size.
But now it seems I can't delete them and replace them with smaller ones. I delete them from my photo album but the URL keeps showing them.
Anyway here's the link to the reduced size format:

Ok, lesson learned: DON'T BUY CHIPS FROM CHINA
but still the quest for NewOldStock Commodore chips grows bigger as time goes on and I bet there are tons of NOS Commodore chips out there just collecting dust, being considered trash by most people.
there should be a safe way to get them, but as I have seen most Chinese suppliers usually want to sell those ICs as soon as possible and try not to answer detailed questions, nor supply pictures.
The last supplier I contected was offering me various C= ICs, but when I asked for the year these ICs were produced, just went around the question.

I'd still like to see what's inside that chip.
The insides of a real SID are way too familiar by now, as some propably know. :) |

How accurate is SID emulation now (ex Hoxs64) perhaps the future is to just have emulation. Unless of course you want to try to invent some new vic/audio trickery... This then can allow the emulators to become even more accurate.
I would not even dream of using a real 64. I know that there are people out there who swear by it but development time is much much quicker and reliable in my opinion using cross dev tools, pc converters etc |

Many of us are still interested in keeping our original Commodore hardware alive, thus our interest in SID chips, 6526 chips and so on. As a purely digital chip, the 6526 should be clonable pretty easily (using an FPGA perhaps?) for those with knowledge about such things (read: not me!).
The SID is another story, though. The analogue part makes it trickier. A chip emulating the SID as good as possible is ofcourse better than nothing (like in the C64DTV but hopefully better!), eventhough a complete clone of the original chip would be better. Here I'm sure a lot can be learned from the various software emulations. I bet there are many chip factories who could pull it off, the trick would probably be to convince them there is money in it... (which there might or might not be, what do I know...).
Perhaps finding valid new-old-stock sources is less utopic?
I fail to see how Algorithm's preference for development in emulators is valid for this thread though. No matter on what platform a c64 production has been developed on it should be tested on real hardware. And personally I always watch productions on the real thing. If someone else only use emulators, that's their business, and then this thread shouldn't really apply to them anyway. |

For development, yes cross developing is much faster and productive. I would prefer to watch the final result on the real thing as well. Alternatively TV-out with proper refresh rate (if possible) would be nearly just as good |

Old thread, but I just received some of those fake chips from ready.
Pics of the internals coming later today. :)

Great! The shipping succeded! I am curious to see what's inside! |

That is very interesting. Please post your finding.
The problem with emulation is that while it is convenient to use it is missing some part of working with real hardware. I'd like still use my good old C64 and C128 in next 20 years at least. |
