No, it doesn't even have a serial port (yuk yuk). If you'd like to turn your favorite 486 into a ZX81 there are ZX81 emulators for Linux, but to my knowledge no one has even entertained the idea of doing some flavor of Unix on ZX81 hardware. Hmm, now thatcha mention it, Linux makes more sense than Windows or GEM, CP/M's already been done, VMS ain't happening here, and I *really* don't want to port MS-DOS ;>) Glen 0/0
