Wow! That is incredible that it still works.
And yet, I acquired a similar 128 in a haul/donation last year
I lovingly called the 128 the Desert Storm edition
, as it was so brown and dirty it looked to have been found somewhere in the desert. Possibly by Indiana Jones himself.
And guess what - it works, too!
I gave the computer to dddaaannn
who lives locally here in Seattle and is also a member of the SEA-CCC
. He was looking for a "project from hell" and I delivered. Hah!
I was watching a video
today of the 8-Bit Guy's where he went through a long scientific experiment of various retr0brighting methods on an even nastier VIC-20. He compared the following:
- hydrogen peroxide/saran/light
- hydrogen peroxide + heat (a suggestion by a chemist)
- vinyl and fabric dye
- engine cleaner (!)
- engine degreaser (!!)
- “usual” treatment of salon creme solution/saran/light
- sodium bicarbonate
- and an ozone generator - something I was not familiar with at all, but found very intriguing.
His initial results were interesting.
Anyway, this test allowed him to produce a matrix of sorts in terms of difficulty and time spent (+ success rates).
Had he used the Ozone machine for 2X the time, it may have produced the same results as the peroxide / salon solutions.
Video is interesting to watch and may give you some ideas. He actually made a series of restoration videos
the topic is such a popular one.
Worth noting that, for all of these methods, it doesn't seem to be a permanent cure. This is 100% anecdotal, but I've heard the plastic will revert back to its yellow states again over time.
