/* This file contains the exported interface to the iec488 emulator.
* The iec488 emulator then calls (modifed) routines from serial.c
* to use the standard floppy interface.
* The current state of the bus and methods to set output lines
* are exported.
* This hardware emulation is necessary, as different PET kernels would
* need different traps. But it's also much faster than the (hardware
* simulated) serial bus, as it's parallel. So we need no traps.
