FYI, I tried the 1401 mode diagnostic M011 today. Results were
encouraging, if not perfect:
- The 1410 mode console output for the instruction to the opertor to
switch to 1401 mode quit after seeing a space character. Should be an
easy fix, especially if I can make it happen under simulation
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 fil
Very impressive. Congratulations!

Yes, as it was part and parcel of every 1410. but I have not tested it yet.
