| 494 | Final Round uses a PROM (not dumped) instead of the PAL |
| 495 | and some discrete logic to combine some of the inputs. |
| 496 | Inputs to the PROM are: |

| 498 | A0 = V1C0 | V1C1 | V1C2 | V1C3 |
| 499 | A1 = V2C0 | V2C1 | V2C2 | V2C3 |

| 501 | A3 = FIX0 | FIX1 | FIX2 | FIX3 |
| 502 | A4 = ~(OCD0 & OCD1 & OCD2 & OCD3) |
| 503 | A5 = V2C6 |
| 504 | A6 = PRI0 |
| 505 | A7 = PRI1 |
