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.

Hmm, I dont want be neagtive but does it matter?
With respect to C64 I assume you as well solder an AMD CPU to the SID socket...
Nice combined effort here btw \o/ |

well, at least I am interested in knowing what the chip really is. I just sent a mail to UMC asking for information about it. Not so much effort in sending an email. |

furthermore, chances are that this chip could be a SID-clone with just a different pinout produced by somebodyelse than Commodore to avoid legal problems. The 6502 and 6501 had about this story back then. Let's see..... |

Replaced the die image with a better one.
And there's absolutely no chance that this piece of junk would have the slightest relation to the SID.
It's just the cheap chinese getting their hands on some random chips, relabel them and sell to those who are willing to offer them some money as there isn't any real danger for them to get busted.

it looks like a simple microcontroller to me, you can easily see the block of memory (wild guess: big block==flash or prom, small block=ram). something like a 8051 derivate or so :) |

Way too much intelligence for SRAM chip. RAM chips in general look like repetitive rectangular patterns covering almost the whole silicon. |
