    Speaking as a sad git who disassembled the code in the Speccy ROM which
    handled tape I/O, I can confirm that it was really simple stuff. Only a
    couple of hundred bytes of Z80 assembler involved IIRC (it was about 15
    years ago!). And of course, the Spectrum ROM is now publicly available,
    isn't it ?

    The question I guess is: why ? :-)
