| How did you test 'em? | | 01/01/70 00:00 |

| Only bad ISR should be able to overload the PC | | 01/01/70 00:00 |
| PC Lockup? | | 01/01/70 00:00 |
| Unhandled interrupts brings almost any machine down | | 01/01/70 00:00 |
| Missing the point | | 01/01/70 00:00 |

| Ha, ha, the capacitors are too big! | | 01/01/70 00:00 |
| maybe they're too small ... | | 01/01/70 00:00 |
| no caps are not too big | | 01/01/70 00:00 |
| did you verify the output voltages? | | 01/01/70 00:00 |
| They were a good deal... | | 01/01/70 00:00 |
| yes, I learned | | 01/01/70 00:00 |
| here is a simple log | | 01/01/70 00:00 |
| here's a log from a real max232 | | 01/01/70 00:00 |
| it does no matter, but | | 01/01/70 00:00 |
| Never mind the logs... | | 01/01/70 00:00 |

| logic analizer | | 01/01/70 00:00 |
| Should Be Able To Examine Using Logic Analyzer | | 01/01/70 00:00 |
| Logic levels | | 01/01/70 00:00 |
| There's really no need | | 01/01/70 00:00 |
| Can it? | | 01/01/70 00:00 |
| Volt meter is good but for rough testing | | 01/01/70 00:00 |
| It could be a bad circuit? | | 01/01/70 00:00 |
| Sometimes totally untested chips | | 01/01/70 00:00 |
| the easiest thing to steal ... | | 01/01/70 00:00 |
| agreed, but ... | | 01/01/70 00:00 |
| Lots of things happens when packaging stolen silicon | | 01/01/70 00:00 |
| ripple, maybe, but proper voltages, never! | | 01/01/70 00:00 |
| where would excessive ripple originate? | | 01/01/70 00:00 |
| are we identifying counterfeits or solving other problems? | | 01/01/70 00:00 |
| not so | | 01/01/70 00:00 |
| maybe, but not an obsolete part ... | | 01/01/70 00:00 |
| Especially for obsolete parts! | | 01/01/70 00:00 |
| The MAX232 was replaced by MAX232A | | 01/01/70 00:00 |
| Lots have already happened | | 01/01/70 00:00 |
| maybe ... | | 01/01/70 00:00 |
| nope | | 01/01/70 00:00 |
| Really? Why? | | 01/01/70 00:00 |
| you have often advocated | | 01/01/70 00:00 |
| In case you haven't noticed ... | | 01/01/70 00:00 |
| some testing results | | 01/01/70 00:00 |
| looks like ... | | 01/01/70 00:00 |
| or they are from the garbage | | 01/01/70 00:00 |
| Voltages? | | 01/01/70 00:00 |
| yes the voltage was 7.79V | | 01/01/70 00:00 |
| Can't use volt meter | | 01/01/70 00:00 |
| I doubt MAXIM would allow garbage out the door. | | 01/01/70 00:00 |
| Counterfeit Maxim parts | | 01/01/70 00:00 |
| How much profit could they have made? | | 01/01/70 00:00 |
| Profit? | | 01/01/70 00:00 |
| Labor isn't the critical factor here, is it? | | 01/01/70 00:00 |
| profit/motives | | 01/01/70 00:00 |
they are counterfeit!! | | 01/01/70 00:00 |
