Default Re: Wireless World calculator project

Thank you everybody!
I found the WW project using the Texas chip but the one I remembered was definately TTL based.
Seems my memory was only faulty in the name of the magazine, Practical electronics, not WW.

The dates fit my recollection, if PE started a year long project in July 72 and sinclair launched their pocket calculator in Sept 72 that would be about installment 3.

That was as I recalled it.

I attach a quote from the editorial of October 1972
