But we must not forgot that cartridge slots are essential for connecting new hardware, and thanks to it we have memory expansions, SCSI/IDEs, MoonSounds, etc... how long could a new MSX survive without cartridge slots?
USB can reach up to 12 Mbps, so, if a clever protocol is designed, the entire cartridge bus can be emulated over the USB cable.
For instance, you don't need to send all the 8 bits of DATA each Z80 cycle... only once every 5 cycles is enough, for a ROM file consisting of NOPs. With hardware extensions it's even easier: OUTs lasts for 12 cycles, so the bandwidth required is smaller than a simple ROM with NOPs. ---------------------------------------------------------------- Ricardo Bittencourt http://www.mundobizarro.tk [EMAIL PROTECTED] Mantenha a paz: Doe um Pretzel para o Bush ------ Uni�o contra o forward - crie suas proprias piadas ------ _______________________________________________ MSX mailing list ([EMAIL PROTECTED]) Info page: http://lists.stack.nl/mailman/listinfo/msx
