Keyboard input currently does not work.
To get this to work, we need to create a new input() function (currently in zxem.c) to handle IN calls.
The keyboard matrix feeds data from 5 different IN addresses:
| Port | Bit | ||||
|---|---|---|---|---|---|
| 4 | 3 | 2 | 1 | 0 | |
| &FEFE | Shift | Z | X | C | V |
| &FDFE | A | S | D | F | G |
| &FBFE | Q | W | E | R | T |
| &F7FE | 1 | 2 | 3 | 4 | 5 |
| &EFFE | 6 | 7 | 8 | 9 | 0 |
| &DFFE | P | O | I | U | Y |
| &BFFE | Enter | L | K | J | H |
| &7FFE | Space | Sym | M | N | B |
These are polled on interrupt (1) every frame. The interrupts are already being called, but no data is being suppled, so the emulator is currently stuck at
