Thank you a lot mpe for the details, very helpful indeed. I look forward to receiving the voltage regulator and test the system!!

Hello all I was wondering if someone could help me with the pinout of a Socket 3. I am a bit confused by the schematics I find online. Can someone confirm which side should I see the attached pinout diagram please? Processor side or back of the board side? Also, is it ok to find 5V on Socket 3 even …

I see, thanks! Well, I hope the regulator is all that is missing. I do have 5V as input so hopefully the output then goes to the VCC pins. I do see some resistors on the ADJ pin so hopefully that will work. Edit: yes, the regulator output is connected to the voltage selection jumper and from the …

Hi Douglar I found the info here: https://www.elhvb.com/webhq/models/486vlb3/sis486ge.html The model number matches and I had no issues identifying all the jumpers. I hope the regulator is all it needs. Again, what puzzles me is that the PCB says 5V/3.3V but then the 3.3 regulator is missing. Indeed …

Thank you Deksor - I shall do and thanks for taking the time to document this. I was just a bit puzzled as the board says on the PCB 3.3V but then it doesn't do that? :) Anyways, I have tested VCC and indeed I don't get anything with the jumpers set to 3.3V. However, some pins do receive 5V (not VCC …

Hello all My first post here. I have purchased a SIS 486G board as discussed in this forum. It was sold as "not working" - it's just to kill time in lockdown! I have a question and I hope you can help me: there are no voltage regulators on my board so shall I assume it's a 5V-only board? From the …
