Ofcourse, no > keyboard without it, so the question is really how minimal do you need to go? The keyboard is not the only thing in the PPI, the slot selection is integrated in it aswell, so... ^_^ Although it would theoretically be possible to let the MSX work with 1 'slot', where the BIOS+BASIC occupy the lower 32kB half and the RAM (a part of) the upper 32kB half, I don't know (doubt, actually) whether the BIOS will let you get away with that. ~Grauw _______________________________________________ MSX mailing list ([EMAIL PROTECTED]) Info page: http://lists.stack.nl/mailman/listinfo/msx
