I’m surprised you didn’t quiz ChatGPT until it refused to answer and/or crashed.
I understand “it” can use very “colorful” language when provoked and poked. ;)

Here is ChatGPT's answer on the first personal computer.

I did a bit of searching on Google Books and there is an article from the June
28, 1972 issue of ComputerWorld that states "Ever since Hitachi introduce the
Hitac 10 as a 'personal computer' in 1969, not only the regular computer

It is also where the terms 'A', 'B' and 'C' supplies come from, since
there were three batteries per radio, grid bias, HT, and heaters. The

A radio that runs off gas rather than plugging into the electricity mains.
Let me explain. The main use for either gas or electriciy in UK homes

In the UK the domestic wiring norm is 13A
16amps where?
In Europe? At least in Germany 16 amps is standard. The Schuko outlets and
plugs are rated for this current.
As an example, the fuse box in my appartment is splitting up the three
input phases (63A each) from the main distribution panel to 3x 3
circuits/16A each.

Rick,
I always appreciate your incredibly informative contributions.
You see, we are back to my original comment. The definition of Personal
Computer is quite fluid. Does it have to be called a Personal Computer
in advertising literature or does any computer that can be used by a
single person, in any environment, constitute a personal computer.

Now that is an interesting refinement. Limiting to 1800 VA, most likely
