Where are all the articles about a TTL designed

Yes I know about (Homebuilt CPUs ring) but that is mostly
today. What about the Late 70's and Early 80's?
Well there's the EDUC-8, based on the PDP-8 instruction set and was published from
1974 to 1975
by Electronics Australia magazine, followed by a number of articles on building
peripherals.

I saw that a few times but I never could find the link again.
I have all the original magazine issues for it, but
you can get them all in book form from
Silicon Chip magazine these days

I suspect you can't get the PCB's any more and the card edge connectors.

The Amateur Computer Club magazines gave me just what I was looking for
as they had prices listed for the chips sold at the time.
I noticed several people were finding very old machines for a song,
(1972-1977) did that happen also here in America?
