WTB: Amiga Mouse and A500/1200 Power Supply

[psxphill]

just as long as you realize that the USB is not true USB but requires a mouse that came with one of those USB adapters. The mouse must still support the PS2 protocol.

I was going to pick up one of these, but not supporting usb would put me off a bit.

With all the chips that support USB these days, I'm suprised they don't support it though.
Especially as they say "any cheap pc usb mouse".
