ZX81 keyboard reading via port 254?

Post by bobs »

Is there any information available regarding reading the keyboard via port 254?

The routine in (new) ROM which returns the row / column lookup values doesn't really do what I'm after. If nothing is readily available then I'll make my own investigations and post back...
