Johngineer ponders this question on the Adafruit blog:
The recent discussion about the “new” 6502 from WDC got me thinking about other old and/or unavailable chips that could use a re-introduction, or perhaps just a process facelift. This post is mainly to solicit reactions and suggestions from viewers like you, but I’ll provide my own example too.
I'm curious - which chips would the members of the community here like to see brought back to life?
Cheers,
Drew
without a doubt and even a nano-seconds thought, the TIL 311, and HP 5082 73XX series.
these to me encmpass all that`s Right in technology.
I`ll get back to you with my list when I`v actually given it some thought 
Yup, all of those fit in the same ball-park, in fact one of them towards the bottom of the list showing the letter "A" is a TIL311.TIL311.
