Managed to source a PSU for the 2 Sharp Hc-4001A handheld PCs I have that isn't from the USA... It's what I call a "Europlug", which means that it'll share voltage with UK, but I need to sort out an adapter for it if I'm not going to be using it with my Europlug power strip! Also, they're not easily accessed right now coz of the move, but I know that they're at least around somewhere, either in my storage unit, or in new flat, it's just a matter of getting things unpacked and placed everywhere!
