I mean that floppy drive today can be only option.
I'm C128 programmer and always using numpad.
When we look at M65 we can see it in two ways:
Retro style - originally looking C65 like w/ FDD
New style - look for example at C128 DL prototypes and adjust cursor keys at CRSR position and originally cursor keys can be replaced by additional C65 Fn keys
Or third: Make <any> case where fits Nexys4DDR with all enhancements together and leave user to select his own keyboard with option USB, PS/2, Commodore and the same option for mouse. Of course it needs USB supporting hub. Separate floppy can have C1565 design.
Me personally have at home Nexys4DDR and want to place it temporary to C1541 case...
