It's great 
Btw, K6 CPUs exist in some cisco routers too. Your note that 90% of the CPUs are not in computers is interesting for those who didn't know it, it's very true. I'm programming a lot of Microchip PIC microcontrollers in assembly or C these times and it's really interesting. They have a RISC design which permits to understand very well how they work and have a complete knowledge of the internal chip architecture, try that on a current x86 CPU...
My current work is on the PIC 18F458 (max 40MHz, costs 6$) mostly used in cars coupled to a CAN bus. |

Cisco routers are bootable computers with added IO for the most part.
THe management on a Cisco is very robust.
I however made note of it.
I also added PIC to the chart.

Good idea to put all of that info on one page. I like it. When you calculated lifetime did you take into account end-of-life date of original manufacturer or second-source companies?

If you note the last colum states SS if it was last made by a Second Source.
I anticipated that most would be made by SS at the end of their life but it turns out it was fairly equal.
production just shifted from commerical to industrial.
By the way the 8008 end date needs fixed (it is actually 1983)

Tundra Semiconductor (www.tundra.com) produced 80c85 until 2000. I don't know if you count 80c85 as 8085 or not, if you do it will extend 8085 lifetime by 10 years.

Yup, that is definately a 8085, I'll make the corrections, thanks.
