Electro data chip question

[watchlover1]

Does anyone know how many known original 25 chip electro data modules are in still in existence? If this question shows up twice with my name on it, it was an error! Opps!!

I don't think anyone knows a definitive number, but the best guess I can make is 6-10. There are at least two P1s out there with these still in the case (regrettably, not working)...the rest are loose modules...maybe rescued from the trash can as souvenirs by Time Computer employees (all ED modules, which, unlike all later Pulsar parts, had individual serial numbers, were to have been discarded as they were replaced during the Great P1 Recall, and the vast majority of P1s do seem to have made it back to the Lancaster factory, where they were re-fitted with the new, more robust circuit board that was next used in the early P2s) . There were at least 500 made; 400 went into 18K cases immediately; most of the rest were held as spares for warranty repairs. Some found their way into the so-called "salesmans' samples". The mass failure of these was the catylst for the breakup of the collaboration between Hamilton and Electro-Data, and all further manufacturing of modules was carried out at the Lancaster facility. Still, given the period, and the complexity, it was a remarkable bit of electronic engineering, even if it was short-lived.

Hey,

i just wanted to mention that it sure is nice having Bruce back online.

I really appreciate these detailed, informed and well thought out posts (not to mention the fact that they are always punctated, gramatically correct, and of mixed case!)

Welcome back, Bruce.
