Largest memory peripheral for ZX81

Preamble

This article was inspired by my question on Retrocomputing, on Stack Exchange, Largest memory peripheral for Sinclair ZX81? and turned into a list of links to vintage computing magazines.

BTW< I’m sure that there was a bigger than 64k memory pack available.
