Amiga Community Collaborates On Restorative Gel To Brighten Your Old Plastic

jamie pointed out an Amiga community that took a discovery of how to restore old computer plastic, super-charged it, and then opened the process to the public domain. Time to spruce up those old dusty TRS-80s in the basement. "All of the initial tests were done with a liquid and we realized that for large parts this was getting expensive, so the next stage was to make a paintable 'gel' version that could be brushed onto larger surfaces. This was tried in Arizona in the sun and the UK under a UV lamp and was found to be just as effective as the liquid. We have now released this to the public domain for anyone to use as we can't patent it and we coined the nickname 'Retr0brite' for it, as it summed up what we were actually doing with it."

    You'd have to be careful with at least PET, because that degrades when exposed to H2O2 for more than a minute or so. So I'd check for possible side-effects before attempting to spruce up your preciousss with this.

    I've always dreamed of what the world would be like if modern computing had gone this route. Imagine your OS as a bank of roms, and your PC as a fully integrated machine rather than a patchwork of PCI cards and third party drivers.

    But in many ways, I'd argue that modern computing has gone the Amiga way: consider how most motherboards now have everying on board, and it's only the graphics card that people might optionally have as an extra for performance. (Whilst drivers can be a pain, they have the advantage of allowing standardisation through an API - the Amiga was moving towards a driver model for graphics and so on, and I'd have thought it a great advantage for any modern machine taking advantage of 3D hardware, so chances are that a hypothetical modern Amiga would have drivers too. Chances are they would've dropped the ROMs too - AmigaOS 3.5 onwards came entirely on CD.)

    Consider: today I run a multitasking OS, with combined GUI and command line. The machine I use has dedicated graphics and sound chips, and everything's integrated on the motherboard. Finally, I'd argue that today's machines are modern Amigas. Compare that to the DOS based PCs, or single-tasking non-command-line and no-chipsets on the classic Macs. Looking back, it's laughable how people back then tried to justify their expensive primitive purchases (e.g., claiming that it was better not to have a GUI), when we see how computers are designed today. The Amiga was written off as a games machine, but what is it that now drives the 3D graphics industry, and arguably the personal computer industry as a whole? Yes, I like having a fast machine with decent graphics in front of me, rather than a boring command line operated piece of business furniture, or a black and white interface that doesn't let me do things the way I want it. The only thing stopping it being a modern Amiga is the trademark.

    Everyone blames Commodore, but let's face it, the early 90s was a rough time for the computer industry. Atari went bankrupt (goodbye ST), Commodore went bankrupt (goodbye Amiga), and Apple would have gone bankrupt too (goodbye Macintosh) if it had not been saved at the last minute by Gates. The industry was consolidating around the Intel 486 platform, and I don't think ST, Amiga, or Macintosh would have survived even if run by someone as brilliant as Andrew Carnegie. What they offered looked unattractive to early 90s computer users who believed alternative platforms were as obsolete as newspapers today, and that everyone should be using the soon-to-arrive Windows95. In fact I can still remember the near-hatred from my fellow students: "You use an Amiga??? Everyone knows companies use IBM, and so too should you. You wasted your money."

    Statistics show that less than 7% were interested in a non-IBM-compatible platform in 1994. That was quite a blow to Commodore who just eight years earlier controlled 40% of the market. Even now I can't believe Macintosh is still alive (3% share). I suspect if Gates focused his energies, and stopped Ballmer from making boneheaded decisions, he could kill-off the Mac fairly easily..... just as he almost succeeded in doing circa 1994.

    Point - Nothing could have saved Commodore. Just as nothing could save JVC from losing its VHS market. The market had changed. (link - http://arstechnica.com/old/content/2005/12/total-share.ars/10 )

  5. Hi - Let the flamefest begin....... by MerlinUK · · Score: 5, Informative

    Hi, I am the guy that wrote the Wiki. Now, I know that there are skeptics out there and I may have over simplified the science a bit so that non-nerds can understand what's going on, but I am open to listen to anyone who can explain the chemistry that is actually going on in a coherent way. I may have made it too simple I suppose. Regarding the ABS polymer itself; consider that black car bumpers and trim are made from (yes you've guessed it) ABS. These tend to go white (not yellow or brown) over a long time in sunlight. This is the ABS polymer degrading to the hydroperoxide via oxidation. The computer parts only go white if you use too strong a peroxide solution, so what is reacting under UV so quickly? My theory is it's the TBBP-A flame retardant which is active under UV and decomposes. There is also the phenomenon of migration, where ingredients can move within the plastic matrix and eventually get to the surface. I believe that the degradation products of TBBP-A migraet through the ABS and this is what make it discolour as the molecules attract oxygen molecules. There have also been comments elsewhere that the site is a hoax and that the photos are faked; if this were so, how could the photographs post in the various forums threads I added to the Reading section of the Wiki this morning be faked? They aren't, simple as......... I know I risk feeding trolls with this but this isn't a hoax. As this uses properietary products as part of the mixture, it couldn't be patented, however, I suppose I could have patented the use of H2O2 with TAED in a use for treating plastic. I chose not to and so it was released for all into the public domain. Don't flame me; try it for yourself. Let the flaming begin...........
