protomech:
Bump for those interested. I'm looking forward to adding a "first production Empulse shipped" entry to this list..

protomech:
It's done! We've now left the "Before Customer Empulse" era.. or BCE for short.. and entered the "Customer Empulse" era.. or CE for short.

Brammofan:
I really appreciate your work keeping track of this, Michael.

protomech:
I'm mostly writing it for my own fact-checking use .. but figure it's a good thing to have around.
