Thanks Diginut for posting these excellent pictures! That makes the forum even more interesting! I´ve also seen your posting of the Chronex module. Wasn´t it Theiss who founded Chronex? I do have a working one of these modules but no case for it. I even don´t know which case would fit. The module looks like it was built in the late 60s instead of mid 70s...

Despite Theiss being the entrepreneur who, in 1969, instigated the development of the first Electrodata Module built by Willy Crabtree, you are correct - he was involved with setting up Chronex in 1971 ... after a protracted legal fight over the P1 patent with Pulsar / HWC that I believe was designed to keep him out of the way whilst the Pulsar was firmly established.

He is still around today, albeit in his eighties. I've got a recent photo of him somewhere ... still wearing an LED watch !!! I'll post it if I can find it ... he deserves more fame for being seminal in the creation of the P1.

Here is a 2007 photo showing Mr George Theiss, who founded Electro-data in 1966 in Texas, the company that built the amazingly complex looking 1969 ED module that evolved into the P1.

Interesting to see below that he still wears an LED - good on him!

Can anyone identify it ??!!

At that angle and resolution it looks like a plastic banded Texas Instruments. Not a terrible choice at his age - nice and light.
