Comment on RC2014 Z80 NOP Tester by Kevin

emalliab.wordpress.com&quot; rel="ugc">@emalliab.wordpress.com</a> This is based on the circuit published by <a href="mastodon.social/@agonzalez&quot; rel="nofollow ugc">@agonzalez, which I believe is itself based on other circuits published online by others too.

Thank you to everyone who posts their designs online :)
