It's time for an Untested Ebay special and this time I have a ZX Spectrum plus 3 to look at. It came with nothing so just the board and I had to bodge together a power supply for the 5v and 12v, it also needs -12v for the rs232, but I am not interested in that at this time.

I also look at fitting a Gotek to the internal and external ports of the plus 3 and I really did go the long way around on this one.
