I/O is already (for the 1415 console) and will be (for tape, print,
reader, disk, telegraph -- whatever) handled by a PC support program,
communicating with the Digilent NEXSYS4 over its USB serial port.
This is covered in the following posts:

What are your plans for implementing I/O? Are you going to emulate a card
reader and line printer using an SD card and a FAT filesystem? Or maybe an
Ethernet connection? It's a batch system; how will you submit jobs to it?
Just curious...
Thanks,
