There's much of that in my chart at:

http://www.classiccmp.org/rtellason/by-generic-number.html

but I have bunches more data to get,  still.

I've heard that,  in particular that Fairchild had made some early TTL in the 
9000 numbers,  I think it was?  But I seldom run across any of that info at 
all,  these days,  and didn't then.  First TTL databook I have goes back to 
about 1970,  and is a TI book with the standard, H, and L series in it only.

Mitsubishi?  I didn't even know they made TTL.  Feel free to pass any info 
along and I'll include it in my charts...
