I have an old Pavilion laptop with a P4. It was decent in its day. Now it’s used only to shell into the servers, and provide other IT related utility.
I don’t imagine HP was selling notebooks in the early 80s.
There was some bizzaro ones in the 80’s.. I worked for LID for a while (Multimeter R&D), then I worked in the calculator R&D (41c if you remember that).. Then notebooks.. both the HP side (Omnibooks) and then post merger..
I run a business now and I hire laid off HPeons in the 50 year plus age group.. We do pretty good..
(I go back to the 9825 if you want to google that, used to deal with ferrite core memory..)
