A 30+ year old device that still works. Kind a nice. Kind a trouble. It sits in stark contrast to the tech that is around today. In the end I will be driving things via HPGL. In looking for documentation I found this wonderful document. The https certificate is expired since 5 days. But peak HP was decades ago. So, yes, this is not surprising. Back then HP made things. And cared for them. Cared for making them well. Which includes documentation and explanation. Today everything is encrypted, and everywhere revenue angle seems to be lurking. Subscriptions are need to run things. Big and old tech companies are rather horrible to deal with. New tech companies mostly too. It is a shame, since technology is amazing. It is of great benefit to people. Back in 1977 the corporate wrapper that HP put around it was reflected in the premium price that was asked for the products. And then bad companies just did not have the service, care or product to live up to the promises. While good companies (like HP) did.
Make Tech Great Again.
Of course that is nonsense. There never is a way back. An egg can not get unscrambled. But still worth looking a the different states of eggs that exist.
