Yellow A4000 front

[metalheart]

@leofoe

I see a yellow front and I want it painted black.
No colours anymore I want them painted black...

:-)

Seriously, I've sprayed computers black more than once, works like a charm !
The only difficult thing is the keyboard...
But you should get a nice black Logitech wireless kb and mouse :-)

I can recommend this, but on the other hand it's a question of taste :-)

Cheers,

I've thougt about a black A1200. A member of this very site posted a very cool black A1200 incarnation he created.

Anyway I'm still stuck on the keyboard part. CDTV keyboards are pretty rare.

I've got a nice white A1200 (it is almost none yellowed) that I keep under a dustcover. It is only used when no direct sunlight can shine upon it. I hope to keep it white for a couple of more years.

Also I have a spare keyboard (still in the mitsumi factory box) I'm thinking about spraying a yellow A1200 using silk gloss paint. If you hold the spraycan around 30 centimeters from the object you get about the same plastic shine as the original case has. The yellowed keys I can replace. But if those keys turn yellow I'm out of options.

Brainwave: Why didn't you use sunblock on your Amiga before?

[billt]

I like Soft Scrub, with bleach, a sink cleaner in USA. I don't know what names this may be sold under where you are, but it's a fine grain gritty cleaning solution.

[Framiga]

I think from both. But from the sun is worst. It gets a few micron into the plastic. That's why you have to rub it off.
BTW: You DID pull out the battery, didn't you?

i'm not sure to have understood the question, anyway . . .

The first battery has been replaced under warranty in 1992-93 or so (don't remember now).

Then another one . . . mhh about 7-8 years ago (during a repair- Paula replaced) and recently i've replaced it after some rework on the mobo.

Why?

Just a idea I have,

If you would polish the keyboardkeys in a machine.
That is a trommel(english?)machine.
It is like a washingmachine which rotates slowly and is filled with for example cork(soft material no duts/scratch).
It is easy to control as the process goes slowly.
Just a tiny bit of the surface has to go from the keys.
I think it will improve the whiteness of the keys without loosen the keysymbols.
what do you think?

[Doppie1200]

Polishing the keys will make you loose the symbols

If I look carefully at my A1200 keyboard upclose I can see the symbols laying on the plastic like a sticker. So you will first polish the sybols off before you reach the plastic underneath it.

It might work if the symbols are much thougher than the plastic.

I did try it with a car polish product(commandant).
It is a very aggressive polisher/cleaner.
I used it on a old A500 keyboard which was very yellowed.
I used a dremel with a polishtool(cotton disc) and the carpolish solution.
It worked allright...yes the symbols do get a bit less sharp but still readable.
And the improvement is whitening was absolutely there.
So I think the sysmbols are tougher then you think to get rid off.
This is why I think a machine like this would work.
And you could do all keys in one go not by hand and 30 minutes  the key.

I dont understand why they made them white in first place..
This would be barely noticable with a dark colour like black, and it looks also better in my opinion..

I would not want to repaint a pc case though.

I would have just cast one out of Aluminum and polished it, but I no longer have access to the forge or casting sand:-D. Wouldn't that look cool though?

My A1200 was white for years until I left it in storage for about a year. It was in there all protected from dust by brown paper and packing tape around the box and in the dark of a storage place but it yellowed anyway. I was very surprised when I took it out and all yellow it was. :-( It's got to be something other than direct sunlight.

Why?

If you keep it in a box, you don't use it. And the battery will get leaking sooner or later. But if it's replaced recently, you have a few years to go. I had my A4000 in a box for years and now my clock is ruined. Argh!

@weirdami

are you sure it wasn't yellow before storage?  do you have photos before/after?

[leofoe]

It was yellow before I put it in the box... So it was too late already.

@leofoe

ahhh! . . .funny . . . understood now the misunderstanding :-)

no, its only the original A4000 case thats in the box . . . the mobo is still running on a PowerTower now. :-)

I've seen computer plastics yellow in dark storage too. It's weird but it happens.
