I didnt mean that the PAL units were only green, I just meant that it seems that green PAL units are easier to get that NTSC ones.

Assembler sold a fair number of all 3 debugger units. Dangerboy bought a pair of them and got a Japanse and PAL one, and then a solo one and that one was a US.

The one that he has up looks to be a pre-production Debug that was made before the main line debuggers were even launched in Japan.
