Have been to busy to work so much lately but have updated the schematics a bit while I work on the PCB layout. Have finished reversing the S3 card I bought and corrected quite a few thing in the VGA schematics. The VGA rom was way different then the datasheet part. Apart from that most of the …

Yes, I have done a couple of BGA designs before. I am doing 6 layers here on this board to make it easier on the power planes. Last timne I did the STPC soc I did it in 4 layers but with all the extras on this time I chose 6 and the price to do 6 layers is way much better now than 20 years ago !! …

It all started when doing some inventory in my components racks..... I found a tray of STP Elite chips with 40 cpu's in it and an idea was born. So now after some weeks of spare time doing schematics and some pcb layout the project starts to look like there is something. Theese are the specs: STPC …

I have done a preliminary design using the datasheet. I bought a pci card that will be delivered tomorrow and I can reverse the signals/ resistors I have doubts on from it. Did about 90% of he layout today. Gotta love how they did the rambus signaling 😀

Hi Madeo, I am in the making of a small x86 computer based on the STPC Elite CPU and had initially done on a trident TVGA9000i graphic chip and was pointed to this thread by another member here. In my original design I have used the ISA bus but I do have a PCI bus available. Can You share any of …

I am building a "new" Dos computer and I am doing pcb layout at the moment. I have done the schematics and was planning to use the Trident TVGA9000i chip since I had the reference schematics for it and it is a simple circuit to use. But since I am using the STPC ELITE Cpu I also have a PCI bus and …
