Hi vogons! I have recently started a collection of various retro computer parts to build a series of different generations of Pentiums through the 1990's. For the most part I have been able to recognize and figure out mostly what I am looking for on each generation I have in my collection. However I acquired a super socket 7 motherboard with an AMD-K6-2/350MFR that I am very curious to get up and running. Not only am I unfamiliar with using this style of motherboard and CPU, but I cannot find any information on this particular motherboard and its power connection requirements. This is a link to a picture of the motherboard on google photos for a high quality image.
It seems to be a Foxconn board with a SiS 530 chipset, but I have not been able to find any shred of its existence through googling it or digging through wimsbios.com. The only thing that comes up is a board that has ATX or both ATX/AT options but not this particular layout and power requirements. If anyone recognizes this board or knows a way to find more information on it I would be very grateful. However, I mainly want to get an ATX to AT adapter to power it on and see if it even posts before putting too much time and energy in to the thing. I can see what seems to be standard AT P8 and P9 connections, but I also noticed a 3rd AT style port that I am unfamiliar with. In my research I am assuming it is a P10, though I am hoping to find some confirmation before I order any adapters or plug anything in.
This is the adapter I was considering getting https://www.ebay.com/itm/ATX-20-pin-to-AT-P8- … 09/270818956893 though Im not sure how the 3-Pin would integrate with the PSU. I do not have the motherboard physically available for another week or two, but Im wondering if there is a 3-Pin power connector on the motherboard next to the supposed P10.
It seems this adapter would be more practical with the power button option, but I am not sure if the 3-Pin would be necessary in this configuration or not. https://www.ebay.com/itm/ATX-to-AT-power-conv … id=160786749586
I am just really struggling finding the right information for this, so I'm hoping someone might be a little more familiar and can steer me in the right direction.
Thanks in advance!
