Perhaps someone from Europe or Asia should chime in on
how the MSX
wave hit their corner of the planet. In the States, it was barely a
whisper.
They were not common in the UK as far as I remember, most people over
here had Spectrums or BBC micros.
Based on the number of add-ons for them published as projects in Elektor
magazine, I would guess they were more common in the Netherlands.
