+ 3. I have a list of commands somewhere. You can get and put screen

Warning: once, after a vacation, I came back in the computer room of the
school. I turned on one PET, nothing. It turned out it was not plugged
in, so I plugged it in (crawling under the table). But I forgot to turn
it off first. Above my head I heard a very loud buzz. I unplugged. It
stopped. I plugged it back. Buzz again, and a very very nasty smell.

I had literally melted some chips on the HYDRA board. They had holes in
them. The PET's main board was also broken. Worse: two other PETs which
were connected via the network only were also fried. Damage, as I was
told: about NLG 10.000 (of about 1984 or so) (EUR 4545).

The first PET, the one I turned on, was also a custom made 8032 with N
keyboard (instead of the usual B keyboard). It never was the same again
after the board swap :-(
