| 66 | These addresses each read a 16 bit register. These in turn |
| 67 | are loaded from the MDAT serial stream and are clocked in on |
| 68 | the rising edge of SCLK. MLD output is used to parallel load |
| 69 | the external parallel-to-serial converter.This in turn is |
| 70 | loaded with the 4 quadrature inputs from each of two game |

| 72 | which are new for LISA and can be read in upper 8 bits of |

| 100 | Bits 1 and 0 of each counter (Y1-Y0,X1-X0) may be |
| 101 | read to determine the state of the related input signal pair. |
| 102 | This allows these pins to double as joystick switch inputs. |

| 150 | With normal (NTSC or PAL) horiz. line rate, the pots will |
| 151 | give a full scale (FF) reading with about 500kohms in one |
| 152 | frame time. With proportionally faster horiz line times, |
| 153 | the counters will count proportionally faster. |
