I managed to collect the original magazines with the Educ-8 articles as
well as scans of the articles, and although the boards are available I
am not sure they would all that useful. The Educ-8 was designed around
both 74 and 8 series TTLs. I did some cross referencing, but could not
locate datasheets on all the 8 series ICs used, so I am not 100% certain
that there are pin equivalent 74 series ICs for all. This might mean a
board reroute.
