--- Quote from: Specmaster on July 04, 2022, 11:30:13 pm --- --- Quote from: mnementh on July 04, 2022, 10:09:16 pm ---<snip> We did. 4 years ago we bought a brand-new Rav4. This is the closest thing in terms of reliability to a Saturn we could find nowadays; it is a pregnant Camry, which the entire world knows is (aside from consumables like tires, brakes & batteries) a 10-15 years zero-repairs vehicle if you do nothing but keep clean oil in it, and more if you actually take care of it. We've had the Saturn since it was brand-new too; almost 23 years now. Over the course of its life, it provided collateral for no less than 3 life-altering loans, which we'd have been completely screwed without. And surviving a freak hailstorm, it paid out $6000 to us which allowed us to move and to close out one of those loans. Aside from a alternator and a radiator, the only repairs it has had are consumables of brakes, tires and batteries. Notice a pattern here...? That is, until now. But I am a mechanic, and I know how to assess... it still has a year or three in it as long as we keep it for a 2nd vehicle. As primary transportation? Hell no. As a toy, or a 2nd vehicle? Hell yes. Same as my brand new scope vs my 2465s and my 54645A. So... just like you didn't know what you were missing not having a civilized semi-modern scope until you got that 54645D, I promise you Vince... you're missing out big time not having a semi-modern phone, or a semi-modern vehicle. I think you've fallen into a really dangerous trap... a belief system built around the whole notion that everything new is cheap crap. The opposite is true with a lot of things; while almost everything nowadays is built to be disposable, many things are built now to be maintenance-free for the entirety of their design life. That is time you don't have to spend doing maintenance like "the good old days". That is a thing of value in and of itself; it allows you to trade your single most valuable asset which is time, for mere easily replaceable money. No matter how you slice it, that is a bargain. As long as you're willing to step up and take that phone call from the here and now, rather than continue hiding out in the past. ;) mnem "…You can linger too long in your dreams; Say goodbye to the oldies but goodies, 'Cause the good ole days weren't always good And tomorrow ain't as bad as it seems…" --- End quote --- Both you and BD do make some valid points but as I pointed out, it assumes that others have the same ability and opportunities at changing their lives and requires them to have the money in the first instance to be to pony up when required. Indeed, the same could go for myself, but what has happened to us along the way is done and dusted, we cannot go back and alter the course of history, all any of us can do is to play the hand that we have been dealt with. I know I dream of all the things I am going to do if my numbers ever come up in our national lottery. :-+ --- End quote --- I know both sides of that equation viscerally, and I explained so very clearly. My point was that as long as you allow yourself to live in that closed-minded belief system that everything new is crap, you'll never ever be motivated to change it. Vince does know better, and the need for a semi-modern SmartPwn is slapping him in the face, and that belief system is literally costing him access to a much-needed job. How could I, as a friend, not point that out to him? It is obvious from here that he needs to do whatever it takes to make that meeting... and as soon as he has a few paychecks under his belt, leverage that into some form of SmartPwn, be it new or used, that is adequate for today's business so he can himself conduct business today, not yesteryear. I know this situation all too well. I've lived it, and clawed my way out from under a similar belief system. It is one of the hardest things to do; we cling so hard to such things. mnem "Humans are unique in that we can create all manner of things to be bothered by, and then spend all our time being bothered by those things." |

Instead let's do something on topic and much more interesting : have these 3 lovely cans with lots of gold plated leads, how sexy. Can't identify them. Does any old beard here have a clue what they are ? First two from the left, the two shortest ones, have 8 leads. The third / taller one has 10 leads no less. Probably some vintage OP-amp or comparator or linear voltage regulator I assume, but well... Google didn't help me here. EDIT : if you know the answer but DO NOT have an old beard, that's fine, I will listen none the less. --- End quote --- Your Harris Op-Amps are attached below. That Texas Instruments CT305 is being a total cunt. Even TI doesn't want to admit to it. :-// mnem Maybe we need to call it a CunT305...? --- End quote --- Thanks BD and Dragon, I knew TEA was worth something ! :-DD I have already downloaded the two datasheet and had a look, then refreshed the TEA page and saw Dragon attached them, how kind ;D So wow... can't believe it, this 2525 is a RACE CAR !!!! 120V/µs 20MHz ?!! :wtf: The 2215 is his little brother, 12MHz 60V/µs, still not shabby eh ! Wow, 120V.... so far all the op-amps I garnered were at best 20V for the TL054.. and have some that do LESS than one volt IIRC ! :scared: So 120V for a vintage part.. just wow....... wow. You can bet your ass I will keep these two little guys preciously ! :-DD Can't help, I now feel the urge to wire them up and see that slew rate for myself ! Datasheet specifies what parameters to use to have a chance of getting that... Too bad for the TI CT305 ... if anyone knows.... it says " 814 " at the bottom... maybe it's a date code, 1981 something ? So if I can find a 1981 scanned TI catalogue, or close to 1981, I might find the datasheet for that IC.... |

Unless someone can tell me what my vintage IC's are, I have the regret to inform the audience that I will have to shut down this forum !! :horse: I don't know how to do that but I will pay BD to do it for me, I am sure he is capable of it, somehow. Just need to find the right stuff to bribe him with. Maybe a pack of floppies for his Apple laptop ! >:D :-DD --- End quote --- To quote the dWagon, the CunT305 datasheet is printed only; look for TI catalogues between 1978 and 1981(the 814 below the model# could mean week 14 1978 or April 81). |

It is my understanding that the iPhone 7 was released Sept 2016 so is already 2 years older so will have the same issues? --- End quote --- Nothing like it. The previous model, the iPhone 6s (first sold sept 2015, end of sale sept 2018), runs the current version of iOS and is still getting updates. The iPhone 7 was introduced a year later and discontinued 2019. Apple guarantee at least four years of updates from end of sale and the previous two models got five and six years of updates respectively. So the iPhone 7 has got at least until Sept 2023 to run, and quite likely as far out as 2025. I don't know what you're saying about the iPad as there was no iPad Air on sale in 2018. There was the iPad Air 2 with an end of sale in 2017, and the iPad Air 3 which wasn't on sale before March 2019. However, both are currently supported on the latest version of iOS and are receiving updates to this day. Only the original iPad Air (EOS March 2016) has fallen off the update cycle, limited to iOS 12.5.5. --- End quote --- I googled how to tell the age of my iPad and followed the instructions and was told to navigate to the General tab, where it gives me the model name and model number, serial number and the software version. There it gives me that model as being iPad Air currently running the latest iOS software of 12.5.5. Then the google site said to navigate to Legal tab, then onto Regulatory tab and then scroll down to very bottom and there almost hidden from view (in a ink colour designed to be hard to read) is the date of manufacture and that date is 2018-02-06. So that is where that information came from. --- End quote --- That sounds like an original iPad Air if it's stuck at iOS 12.5.5, which was on sale from Oct 2013 March to March 2016 The manufacturing date could be later (e.g. warranty replacement 'parts' units as opposed to 'sales' units) but that's not the year that one would use in describing the model). What's the model number physically printed on the back of the machine? A1447? |

All you have to do is Google the model number LASER-engraved on the back of it; there are shedloads of sites devoted to itemizing and cataloguing in teeth-aching detail everything Apple has ever made. My Daughter's A1893 6th Gen 9.7" iPad is often confused with the iPad Air 2; it can in fact be used with that model Otterbox. mnem :-/O |
