| Any value to a fast 8255? | | 01/01/70 00:00 |
| Fast 8255 | | 01/01/70 00:00 |
| 8255 breakeven volume | | 01/01/70 00:00 |
| there are a few things ... | | 01/01/70 00:00 |
| 8255 vs 6824 | | 01/01/70 00:00 |
| too many users failed | | 01/01/70 00:00 |
| Reconfiguration | | 01/01/70 00:00 |
| Yes, one had to know how the device behaved. | | 01/01/70 00:00 |
| the 8255 was tough to learn, but in its crummy way | | 01/01/70 00:00 |
| peaple would rather forget the 8255 | | 01/01/70 00:00 |
| Why do you suppose that is, Jez? | | 01/01/70 00:00 |
| raison d'etre | | 01/01/70 00:00 |
| Main reason, I think | | 01/01/70 00:00 |
| There are other reasons, too. | | 01/01/70 00:00 |
| Thanks for sharing your experience! | | 01/01/70 00:00 |
| There's also a large replacement part market. | | 01/01/70 00:00 |
| but for that you have to compste with Intersil | | 01/01/70 00:00 |
| Intersil still only offers the \'80\'s technology | | 01/01/70 00:00 |
| May be I am wrong, but... | | 01/01/70 00:00 |
| It hasn't got the same sort of ports as the 805x | | 01/01/70 00:00 |
| Yes, you are right | | 01/01/70 00:00 |

| Why would a novice build a PCB? | | 01/01/70 00:00 |
| Products and packages | | 01/01/70 00:00 |
| gee ... and I've never before heard of Tekmos ... | | 01/01/70 00:00 |
| quick thoughts | | 01/01/70 00:00 |
| You're on the right track, EXCEPT ... | | 01/01/70 00:00 |
| on analogy... | | 01/01/70 00:00 |
| 8255 in India | | 01/01/70 00:00 |
| It makes little sense to teach 8085, or does it? | | 01/01/70 00:00 |
| I Agree | | 01/01/70 00:00 |
| Do not attend | | 01/01/70 00:00 |
| Every Collage | | 01/01/70 00:00 |
| Not "College Think" | | 01/01/70 00:00 |
| just had a thought - Lynn, Jez | | 01/01/70 00:00 |
| Enhanced 8255 | | 01/01/70 00:00 |
| If all one could get is PLCC ... | | 01/01/70 00:00 |
| well i have come up with a way. | | 01/01/70 00:00 |
| There is a problem with FPGA\'s ... | | 01/01/70 00:00 |
| nRD is needed in the 8255 as a clock | | 01/01/70 00:00 |
| Perhaps that\'s because they use latches | | 01/01/70 00:00 |
| on using undefined states | | 01/01/70 00:00 |
| grounding chip select is risky | | 01/01/70 00:00 |
| but what if it is grounded? | | 01/01/70 00:00 |
| clinging to the past | | 01/01/70 00:00 |
| Don't forget the Maxim/Dallas parts, they use 5V0 | | 01/01/70 00:00 |
| as usual apples and oranges | | 01/01/70 00:00 |
| you need to see it from Richard's viewpoint | | 01/01/70 00:00 |
| he has the right to his viewpoint ... | | 01/01/70 00:00 |
| There's room for disagreement on that ... | | 01/01/70 00:00 |
| "development" and "replacement" are different | | 01/01/70 00:00 |
| well, for the (in)famous "universal board" | | 01/01/70 00:00 |
| If there's a market, it would be for THE part | | 01/01/70 00:00 |
| again mixing parametres | | 01/01/70 00:00 |
| the value of an improved 8255 in legacy applicatio | | 01/01/70 00:00 |
| I'm not so sure about that one ... | | 01/01/70 00:00 |
| OK that was just one - bad - example... | | 01/01/70 00:00 |
My point and point of view, all along has been ... | | 01/01/70 00:00 |
