    The vc-1541 (the cream one) may be a vic-1541.  This revision of the '41
    uses different timings that don't work with the c64 (ie the delays during
    badlines on the c64's video IC).  You might try turning the video chip off
    (cant remember the poke), and then blindly loading $.  Then runstop/restore
    to see if it read anything :)
