There's a response from the X68000 author, which using Chrome's translate says:
"I'm interested in DE10-Nano rather than MiSTER.
This time I struggled to
rewrite the FD emulation in hardware, but if it
is possible to do disk emulation on the
ARM side because DE10-Nano can use Dualcore ARM that is more powerful than Nios, disk emulation can do
much part to software You
But is it easy to write an ARM program of DE10-Nano?
Because there is no keyboard (PS / 2) I / F, I
think that I will emulate using the USB KB from the ARM side, but in that case
control of the USB is required, and
it is expected that it will be difficult without some sort of OS You are
If so, what kind of OS do you use? . ."
