Yes i think you are right.
What about the 4483 on front and back? Year 1983 & weel 44 - but this would be unusual? |

TI used YYWW format from late 60s. think the 4483 is to do with a die or production batch number
also by 1983 they mainly used the Philippines plant for most of their Asian chip supply
here is picture of another found on this site 8048
Seeing this picture 4483 could be testing code for product |

I suspected they may be reproductions when I got them. You never know these days with all the fakes coming out of China. So I destroyed one by popping off the lid to make sure they were genuine.
That one will be going to Birdman in June to be photographed. I'll add those photos to my ebay ad as soon as I get them.
As for the manufacture date, I'm just not sure. I would like for anyone who knows more about these codes to please post a comment.
I have seen a couple others over the years and bought them when I could. They are very rare.
With everyone chasing the 4004, few seemed to even notice these. |

I suppose that is because this is really a micro controller
released in 1974, three years after the first CPU, the Intel
4004 (developed by January 1971) and released for the
general market in Nov. 1971. |

No, actually it's because Intel designers were greedy and jealous of TI's patent. They promoted a deceptive story that fooled many for over 40 years.
Intel presented their case and lost. Your not convincing me that they willingly paid TI over 100 million in royalties.
If you've got proof otherwise tell it to the judge. I'm sure the guys at Intel would love to see it also. |

I apologize if my response seemed harsh. Actually you presented correct information. The TMS1000 is technically a microcontroller (microprocessor with an onboard program memory added) and the release of the commercial version was in 1974. The keyword here being "commercial".
The important detail you didn't mention though and Intel will never mention is that the TI beat them to the goal of putting the microprocessor on a chip. That chip was the TMS1000, which was produced as a military grade part and for TIs own internal use. Ti's target just wasn't the commercial market at that time.
The TMS1000 developers and microprocessor patent holders(Gary Boone and Michael Cochran) were typical engineers and as anyone would expect they had no interest becoming showmen or celebrities. This is something Intel used to their advantage and began a campaign which continues to this day to convince the world that they were the creators of the microprocessor. The simple truth is that they were the first to commercialize a microprocessor.
The Intel 4004 was mass produced and there are many of them still around. The same can be said of the commercial version of the TMS1000. Both are important chips in microprocessor history. |
