Interlude: A Matter of Conversions

Thesis: Just over two decades after Apple changed computer design forever with the first iMac, the technology inside is best described as “quaint”. In 1998, the decision to be the first personal computer to jettison the floppy disk drive was as prophetic as adding a USB connector, but nobody expected the standard cathode-ray tube monitor to itself become completely obsolete a decade later. Downloads and streaming removing the need for CD-ROM drives, the hard drives becoming increasingly obsolete, and more actual processing power and functionality in the first generation of iPhones…22 years after that first 233mHz Bondi Blue iMac hit computer stores, there’s not a lot that the innards can do that can’t be done faster and cheaper with current tech, but that wonderful, beautiful polycarbonate shell is a different story.

Thanks to two former school computers gifted at the beginning of the last decade and a client who really wanted them as plant enclosures, it was time to go back and try making new iTerrariums from two stages of the iMac evolution: one converted from the first-generation Bondi Blue model circa 1998, and one from the much faster 400mHz Graphite model from 2001. Both had the classic handle on the back cut out and used as an access door, but the Graphite had one ring of ventilation holes around the handle that made its conversion much easier. The Graphite also had a plastic cradle that suspended the interior up against a support plate that also held the monitor and the speakers, and since the plate was polystyrene, it didn’t survive its slow journey through the Twenty-First Century in one piece. The original one disintegrated while attempting to fit glass over the monitor aperture: thankfully, I had a spare.

In both cases, quite literally, the bottom plate was relatively easy to waterproof and ready for holding soil mix, even around the ports for the power input and the peripherals. If anything, the Graphite had a smoother bottom thanks to that support cradle, but both were finished, sealed, and readied for the client.

As for lighting, previous iTerrariums used standard 17x LED bulbs because waterproof lights of that intensity didn’t exist at the time. Ah, how the world changes in less than a decade. More light, less heat, and a significantly reduced risk of electric shock, as well as a more modular system where the entire enclosure can be moved much more easily.

In any case, these won’t be the last dead tech conversions to come out of the Triffid Ranch, but these will be some of the last iMac conversions for a while. Worthy iMacs may not be as rare as Eighties-era console televisions, but they’re getting there, and when I go through the last available shells, that’ll be it. The important part is that the client will be happy, and now it’s time to move to other projects.
