It is with great sadness that I must announce the death of my Turbo button, while working on it, the button itself got stuck, and I cannot seem to get it properly unstuck. While testing I didn't see any smoke coming or anything when I was pushing it previous to it getting stuck, but none the less, I …

Can you post a pic of what the back side of yours looks like? I am guessing that there were two different models. One with just the lights, which you have, and one with the LED display as well. If your has all those little jumpers in the back, then you do have the LED display. The thing about the …

As you can see in my other post here: https://www.vogons.org/viewtopic.php?f=46&t=53478&p=577899#p577899 , it seems I've got my turbo button working and everything wired correctly now. However, I am missing the LED panel which should or at least looks like it should go right behind the plastic …

does anyone know any program for DOS or Windows 3.1 that monitors processor speeds in real time? So I can test the function.

So, I made some progress through some more trial and error, the turbo button works now, however the led still doesn't display the speed. https://scontent-ort2-1.xx.fbcdn.net/v/t1.0-9/18010756_10209281767585389_5917449507447214988_n.jpg?oh=79459194340eb5aefc0d03353b369612&oe=5984A752 The green light …

t seems to be incorrect as CN14 is where I currently have the power LED connected and it works. It didn't work anywhere else I tried it. Power LED header is in 5pin "keylock" section, google it, it's standard for all desktop PCs of that time and if your green power LED is lit now then turbo switch …

actually, I just looked at the maunal: http://motherboards.mbarron.net/models/486pci/ls486ec2.jpg it seems to be incorrect as CN14 is where I currently have the power LED connected and it works. It didn't work anywhere else I tried it.

Have you at least downloaded the manual from second link? It says that CN13 is for turbo switch, a two-pin header and CN14 is for turbo LED (switch state indication). If your 7 segment LED display is not lit, it probably means that it's not connected to a 5V rail, AT PSUs have a 2pin connector …

The color of the wire is mostly the positive side.. The white wire is the negative side.. It could be possible that the leds are just worn out.. Maybe its better to test those first, so you know they are working fine.. Then have to look on the motherboard where to connect them to. This may sound …

I recently bought a 486 machine from a guy and it works perfectly, only problem is the turbo button, as well as the LED light and speed display for it does not work. even though this is not crucial, it would be cool to get it working. I am hoping it's just wired incorrectly. I am having trouble …

What does that mean? I actually pay for dialup, so I figure that once I get the modem working, I just dial with trumpet winsock? Am I missing something?

to get one the internet the way it would've been done back then, especially with 3.xx!

Hey, sorry I am asking this before making an introductory post, but I am busy and gotta ask this question, I will write an intro tomorrow. Anyways, I just bought a vintage computer with an AMD486 processor, sound blaster 16, and 1mb ATI video card, works great, except the turbo button doesn't seem …
