I don't have a large test sample, but a case and speakers treated with 303 (applied multiple layers) yellowed again after 2.5 years at room temperature (it was also covered with a black plastic - didn't help).

Well if you find a paint that has similar colour like the plastic and similar matte shine, then that would definitely fix the yellowing :-). The yellow stuff would not be visible under the coat of modern UV resistant paint. That's definitely not something you want to do to rare pieces, but for a …

Is there any difference? :) i will try out the wax, looks more promising for the longterm usage. No difference yet. It's placed right behind the window and it gets enough sunlight every day. So I am hoping to see a difference in few months. I also think that the wax is potentially better because …

It dries quickly and then you can polish it, it's not visible at all and it's the most safe wax you can use. It has a very slight shine to it, but in case of plastic you can't tell the difference at all. It should be completely safe to almost any surface, that's why it is used to preserve even very …

I started now a test where one part of retrobrighted plastic is covered with electrical tape - this will prevent oxygen access. And then I also applied Renaissance Wax to one strip, 303 to another and then I left one untreated and original condition. I will leave it near a window and hopefully I …

I've given my retro plastics the 303 treatment but only started doing it about 6 months ago - impossible to know if it will have a positive effect but it can't hurt I don't think. Any success? :) i think here would be more important to protect against the oxygen, the radiation (uv, heat) works just …

I guess we can expect delays in the current situation - since these cards are produced in Russia. Most payment methods to Russia are blocked (including PayPal) and SWIFT payments and airplanes basically stopped flying there + big delivery companies such as DLH or Fedex suspended operations in …

Thanks. FTP - I am using WS_FTP, but that's just the first FTP client I found, there are many others. I used a simple network switch (no router) to connect my Windows 10 notebook with the retro PC. In Windows 95 you just need to set up the TCP/IP in the control panel. I just picked a manual IP …

I have finally finished my first retro build. I had the same PC case back then in 1996 and it took me some time to find it for sale. Originally at that time I had a 486DX4 120MHz, but I decided to build a Pentium 233 MMX for a more versatile DOS gaming machine. Specs: - Pentium 233 MMX - TMC AI5VP …

I wonder if using 303 Aerospace Protectant will help to prevent yellowing again - it's a UV protection made for plastics (used in boat / automotive industry). It's easy to apply and easy to remove - although that's not necessary because it doesn't alter the color. I recently did retrobright on an …

This is so accurate in my case that it’s scary 😀, I am on step 23 now.

I opened up two AT power supplies, here are the pictures for archival purposes. Both are 200W, but the right one looks like better quality (better heat sinks, more components, ferrite core on the power switch cable, ...), although the solder on the monitor power connector looks a bit dangerous and …

Can I still use the regular AT power on switch with this? Do I just connect the corresponding 2 pins on the board with the existing switch?
