@inkican So the first issue ads include an ad from "James" electronics in Belmont. Is this Jameco under a previous name?
Also an ad nera the back indciates "tri-share is a trademark of National Semiconductor". Is this a typo? Or perhaps did National call tri-state "tri-share" back September 1975? Or is it something else altogether? National always loved their tristate trademark, that's for sure.
