"Were those intended for home use???"
No, I don't think that they were intended for home use, although some may have ended up in homes.
The Sony "portapack" was popular with sports coaches, golf swing experts, schools, industry and perhaps a few home movies were made with these machines.
The Ampex was semi portable... about 95 lbs, but with a handle on both ends, likely was used by some tv stations to record remote events.
I remember reading once that Hugh Hefner had a 2" Tape, quad head color Ampex at his home, in days before VHS and Beta.
