| Bob, clearly you need to read on port latches in t | 01/01/70 00:00 | |

| this is why the \"adult\" ICEs are for... | 01/01/70 00:00 | |
| no ICE I know of can show the port LATCH | 01/01/70 00:00 | |
| Optimise? | 01/01/70 00:00 | |
| sure | 01/01/70 00:00 | |
| Now, as discussion of optimization started | 01/01/70 00:00 | |

| I would never ASS U ME | 01/01/70 00:00 | |
| that OKI part... | 01/01/70 00:00 | |
