| 285 | - Centronics port finishing touches: verify where the paper out, slct/err, and |
| 286 | IPP pins map in memory. The firmware doesn't actually use them, but they must |
| 287 | map somewhere as they connect to the ASIC. |
| 286 | 288 | - RS232C port and Modem "port" connected to the DUART's two ports |
| 287 | 289 | These are currently optionally debug-logged but don't connect anywhere |
| 288 | 290 | - DTMF generator chip (connected to DUART 'user output' pins OP4,5,6,7) |

| 316 | 318 | - Figure out the keyboard (interrupts are involved? or maybe an NMI on a |
| 317 | | timer/vblank? It iss possible this uses a similar 'keyboard read int' |
| 319 | timer/vblank? It is possible this uses a similar 'keyboard read int' |
| 318 | 320 | to what the cat does) |
| 319 | 321 | - get the keyboard scanning actually working; the VIAs are going nuts right now. |
| 320 | 322 | - Beeper (on one of the vias?) |
