How expensive is considered an expensive chemical? A bottle of 32oz 40 Volume Developer is about $4. Its about $9 for 100ml of the stuff here in New Zealand, you would need a few bottles of the stuff to do a C64 (100ml is less than half a cup!) The 8 bit guy appeared to be using much larger bottles …

There are a couple of youtubers that have success with UV-A / UV-B lights or even bare blue LEDs that are normally used with the yellow phosphorus, in combination with hydrogen peroxide. I’m not sure if UV-C has the same effect as it doesn’t occur naturally (especially indoors). I can confirm that …

the yellowing comes from bromine in the atmosphere binding to plastic over time. I thought it was the sunlight that triggered this though? I have a breadbin C64 in its box and its got zero yellowing. I have a macintosh LC II that has yellowed on top, except where an object was placed over it and …

As I said, im aware of the dangers, and using enclosed is totally safe. Anyway, the keys in te eraser have had 2 hours and no visible effect. Why are some people saying that sunlight works? I thought the sunlight caused the yellowing to begin with? I was more interested in the UV-C for producing …

Firstly, IDK if there is an official thread here on retrobrighting techniques, but I believe UV light alone has been shown to work, as has ozone without the need to buy expensive peroxide or chemicals. I was thinking I should try taking it one step further and use a high energy UV-C tube. Please …

Im sure the older bios revision allowed more drive options to select, but anyway I have made some success but its still not 100% working right. I did this CMOS hack here https://www.youtube.com/watch?v=z9YXyfG0Vf0 I was able to get windows to see the drive as a 5.25 drive, but it would not properly …

Im trying to use omniflop on my ASUS P5Q Deluxe motherboard running windows 7. My BIOS setup does not allow me to select a 5.25 drive, only a 720K or 1.44MB 3.5 inch drive. The instructions for installing omniflop say it does not matter if you cant set the drive type in the bios, however it will …

thats cool, ill do that and check for listings. I should really get a collection myself mind you.

They often contain an Am5x86-133, which can be replaced with an Intel DX4, if that is what you are after. OK thats cool, i did not know you could buy …

You would be surprised how easy these parts can actually be obtained in china. Just look at all the products for Commodore64 that are still made. Anyway, lets assume the sockets are not made anymore, there are probably plenty of dead 486 mobos out there that a socket could be removed from and …

Here is the type of voltage adapter im talking about incase you are wondering.

Does anyone know where you can find these? Ive got a OPTI 495SLC motherboard and would love to install a DX4-100 CPU in it if possible. I have seen there these sockets that plug into the motherboard with a voltage regulator on board to cut the 5V down to 3.3V so you can install a later CPU that runs …

Just by reading through the page, it explicitly states Supports 80487SX,80486SX/DX/DX2/DX4 at 25/33/40/50/66/75/100MHz , so you just have to scroll down to see the jumper settings needed for the speed you want. Yes I see that, only thing is the board does not have those jumpers quoted to lower the …

Looks the same as in the photo in the link below with the manual: http://www.philscomputerlab.com/biostar-mb-1433.html I dont see any voltage regulator, nor do I see the jumpers required to lower the voltage. Are there a few variants with this model? Would be great if It was capable. Is there such …
