Long-Term PC Preservation Project?

failcomm writes "I've been talking with my son's (middle-school) computer lab teacher about a 'time capsule' project. The school has a number of 'retirement age' PCs (5-6 years old — Dells, HPs, a couple of Compaqs), and we've been kicking around the idea of trying to preserve a working system and some media (CDs and/or DVDs), and locking them away to be preserved for some period of time (say 50 years); to be opened by students of the future. The goal would be to have instructions on how to unpack the system, plug it into the wall (we'll assume everyone is still using 110v US outlets), and get the system to boot. Also provide instructions on how to load the media and see it in action; whether it is photos or video or games or even student programs — whatever. So first, is this idea crazy? Second, how would we go about packing/preserving various components? Lastly, any suggestions on how to store it long term? (Remember, this is a school project, so we can't exactly just 'freeze it in carbonite'; practical advice would be appreciated.)"

Wouldn't that teach them something about history, or give them some understanding of how different our culture was compared to their culture?

      This kind of activity is educationally relevant because it allows students to feel like they've contributed something to the world or done something cool.

I managed to fix the situation by telling the users that when they turned off the terminal at the end of the day, they should set the entire thing upside down. The idea was to use gravity to redistribute enough of the electrolyte so that the dielectric performance was improved. It worked like a charm, although I got a unfortunate reputation for being something of a mad scientist. People who couldn't remember my name would refer to me as "that guy who had us turn our computers upside down because of those jelly-roll things."

      So although it is a long shot, it might be worth storing the things upside down. In part this might counteract the migration of electrolyte that has occurred over the years, and when they unpack the thing and set it upright, it will counteract any migration of electrolyte that occurred during storage -- presuming any is left.

      I wonder whether sealing the circuit boards in wax might help with the outgassing problem. There's an epoxy that is specifically designed for pouring over circuits, but wax could be undone after the capsule was opened -- although it would be messy.

      In any case, the first step you should take is to restore the computers to as close to perfect working order as possible. You could desolder the capacitors and install brand new, high quality replacements. Also pay attention to connectors that need replacement. Then you should prepare the computers for storage. Speaking of connectors, it might be best to unplug as many connectors as possible, to prevent metal-to-metal reactions. Disassemble everything, leaving clear instructions about how to put them back together again.

      It occurs to me that it might be worth making the time capsule airtight, adding valves to it, then purging and pressurizing it (slightly) with a inert gas. Other than the shell, you could probably get most of what you need form a welding supply store. Purging the air of water, oxygen and miscellaneous pollutants would reduce the chemical degradation of the equipment. Pressurizing it might retard the outgassing problem for a few years. Although it is unlikely that the capsule would remain pressurized after decades, you'd have to put a warning on it if you don't want some future person to blow their head off. You probably should put a warning on the capsule anyway; I agree with the other poster who noted that after several decades, you could end up with a box of gaseous poisons, and I don't think people will become more careful about this sort of thing.

Modern components simply are not engineered to this level of reliability, and for good reason - they're going to be obsolete in 5 years, so it makes no economic sense. You'll have to do at a lot of detail work to try and assure that the machine will even start:

    You will have to replace every single electrolytic capacitor (in everything - mainboard, PSU, every drive, monitor, mouse, keyboard and speaker amp) with solid-state versions. Electrolytics dry out and it's very unlikely that anyone other than a computer historian would think of this before powering the computer up. Altair 8800s and Imsai 8080s from the late 1970s are now to the point that their power supplies and electrolytics must be replaced for them to work reliably - don't expect your machine to fare any better.

    It's also a safe assumption that the lubrication in any rotating media drive will be gone by 2060 - not sure how to deal with that other than providing lube in a hermetically sealed package along with instructions to disassemble the CD drive and apply it.

    How are you going to have your data last? Tapes and hard drives will demagnetize by 2060. Flash may have a prayer; Your best bet is to get some extremely long-lasting batteries and interface a microcontroller with a plugged-in thumb drive. Store the data along with error-correction codes on the drive. Have the system wake up every ten or twenty years and "scrub" the drive, reading every block and writing it back. Do the same with the system's bios EEPROM - the system will be useless if that gets killed by a cosmic ray. You should also pay to have data CDs gold-mastered - redundancy is the only way to go here.

    The display is another problem. The only technology I'd really trust to just work without needing any repair is an LED display; LEDs can run continuously for decades. After the LEDs, a CRT is probably the best bet (despite a decent one having hundreds of precision electrolytics that'll need replacing) - After all, we've got examples of working CRTs from the 50s and 60s. Newer technologies haven't been around long enough to prove themselves yet.

    Get a corrosion resistant, hermetically sealed package for the whole kit and kaboodle and flood it with a dense inert gas like SF6 to keep anything from growing. Thoroughly sterilize every square millimeter with a hard UV light just to be safe. Put the HDD in its own sealed bag full of nitrogen if you include one.

    For power, your best bet is probably a primary battery (Mg-Cu) with seperately-stored electrolyte feeding an inverter - The shelf-life is "forever until mixed," at which point the machine will probably have a few hours of power depending on how much you include.

    Assume that the people who recover the device will still speak your local language and have libraries where they can look up terms such as volt/byte/etc. If they can't, I doubt there will be enough of civilization left to care about some artifact from before The Fall.
