I'm looking for the Synertek 6516 data sheet, and
Synertek technical
notes 34 and 40. The 6516 was to be a 16-bit extension of the 6500
family, years before the 65802/65816. Synertek published a data sheet
in mid 1978, but the part was never put into production.

Not entirely.
To my understanding, the 6516 was Magazin Vapour
Ware.
A red hering just brought up from time to time in various publications.
I seam to remember an Micromag and an Kilobaud article, both mentioning
that there is no evidence of such a CPU, and all is just whishful
thinking.
That's not inconsistent with the idea that Synertek may have published
the data sheet and even a few tech notes. Many data sheets have
appeared for chips that haven't.
I never saw a data sheet or tech notes myself, but have heard claims
from other people that the data sheet did exist.
