I have laser printed the article page on magazine paper and iron transferred to PCB, etched one of these, Thump a Tron.
Drilled and put all the parts in, works pretty good.  Some errors in the original article, the UJT transistors are backwards.
Gnome is next on my schedule, wow all that in one LM3900, he was a great designer.

Which issues are they?
