I guess another Apple 1 is up for Sale
When I first started the registry, remarkably few Apple 1s had been powered up in any recent timeframe. Since then, a lot more have been turned up, so to speak. I started just logging the most recent time each one had been known to be operated. Since replacement components are still available, I currently consider the number kind of meaningless, since with little to a lot of effort, any one of them could be operated. It's not like some vintage airplanes or cars, where some key components may not be available to repair a broken unit. regards, Mike Willegal
Well some original components are still available, not all. Some similar replacement parts are avail, but non date correct are avail. It is still exactly like a vintage car because you may have to sacrifice a less rare model to get things up and running. Going forward it's more about originality for a running unit and what original accessories are with it. Too many of the known working Apple-1 have replacement electrolytic big blue caps with date codes in the 80's. Also we are starting to see some of the "Apple" defective boards coming out. Some of them never ran. I'm helping someone out with one of those now. It's a lot more than simply replacing components. corey cohen uǝɥoɔ ʎǝɹoɔ

One more thing also. Many Apple-1 boards had mods or damage so the cleaner, less molested, the better is becoming important. corey cohen uǝɥoɔ ʎǝɹoɔ

The date code component thing is sort of like worrying about having a numbers matching car, it matters to some people a lot more than to others. Once it is debugged, the computer operates exactly the same way if it is built with all 80's era components or all 1976 era components that were originally stuffed into the board by Steve Job's sister. regards, Mike Willegal

I can see the thought behind matching datecodes on the IC's Because that's the first obvious thing which is noticed, Which is something I look for in my part bins, but I just keep them mixed in together per part# as I don't sort them like that on my inventory list But there still an issue with transistors, eg. MPS3704 [TO-92] There's no discernible identifying datecode technique on the small TO-92 plastic packages, Not that I'm not aware of at least to know if its' 70s or 80s or 90s, etc There is on those metal cans such as the TO-3, TO-18, etc This problem extends to the resistors and diodes too, Even NPO caps, unless you physically pulled them from period equivalent equipment, So how far do you go with matching components, it's won't ever be 100% As for the original electrolytic caps, I wouldn't always take a chance with NOS 40yr old electrolytic caps sitting on a suppliers shelf. just saying, Dan

To me the repro's are just as good as the original :-) The IIGS is the sexy one.
Actually I have found a great degree of reliability issues if the restoration does't check all the boxes. The original design is pretty marginal and when stuff ages or drifts out of spec, the boards won't work as well as a replica with newer components. Fortunately most aged parts can be electronically restored if you catch them early enough and know what your doing. corey cohen uǝɥoɔ ʎǝɹoɔ

yea its called Electromigration very common with 60s,70s and many 80s components mainly due to the metal layer not compensating for thermal dissipation modern components don't suffer from this and the oven is your friend
