Agh. I had to pay SEK 200 for mine. Damn you :)

It's a beautiful machine, especially with that power-on chirp and the
nice, green screen.

I'll compare these with the markings on my EPROMs. I still don't have
a way of dumping the contents I'm afraid.

You could wire a RS-232 interface. The userport pinout is almost
identical to the C64, except for the +5V that you'd have to tap from
somewhere else.
Ruud and André might have a few suggestions regarding an IEEE-488
connection.

Why did you do that? Anyway, from the PET index:
IEEE-488 USER PORT

I'd say you stand a good chance of toasting the user port 6522 and/or
the IEEE-488 drivers.

I think these are the same dates as my model, but I'll make sure when
I get home. Mine was made in Germany, what about yours?
