It looks like a $1 toy
What an insult

I have asked many times on various forums how the hell do you get the required negative voltages needed to run an Amiga/C64 motherboard to a deafening....silence lol
That's REALLY easy, at least for an A1200. Use a PicoPSU (google it). It's a ridiculously small ATX PSU that uses a 12V DC input. All you need now is a 12V laptop battery. Of course, I have no clue about how much power an A1200 with accelerator uses (a modest '030 maybe). This
might be doable.
