It's just HP and HPE split up. HPE took all the nice enterprise stuff, plus the supercomputing business (they own Cray). HP took the consumer stuff, and proceeded to milk as much as they could.
HP semiconductors went HP -> Agilent -> Avago, now broadcom.
Unfortunately, in the same era, their software was almost always complete crap. I think the same rigid processes and controls that allowed them to make great hardware were the reason their software was awful. Their rigid processes made changing the software difficult, so it was harder for the devs to improve (and they usually didn't bother).
No, seriously, sometimes they caught on fire.
