Sorry to bump old thread I came across this thread trying to identify a board I recently picked up, which appears to be the single cpu version of this board. https://theretroweb.com/motherboards/s/sprint-manuf.-co-mb-p5n-sp It looks like you have got the board functional with your bios witchery, I …

Ah, thanks for that suggestion. I had some concerns about the hole height as well. Might just adjust that later when I got time.

Yes, extensively measured with a scope. Most boards anyway fail to drive proper 5V on their DRAM address lines for long. Also cross checked to the fact that Compaq and others like Memory Masters are also using a bunch of these chips on 5V modules. https://www.ebay.com/itm/124443425899 So far I've …

Just a quick release announcement here, nothing fancy. Made a 16MB SIMM/SIPP dual function module design. Perhaps you'll like it.

I see, thinking it may be less trouble to just finish my own footprint than to tie the project to a license. I basically public domain all my work. Total open source, no strings. Lemme see what I come up with. May reconsider. :-) appreciate it none the less. That's the strangest response I've seen …

Wow this is pretty amazing! I'm surprised that it is an Award BIOS and not AMI like mine originally was. What chip does yours use for the SIO?

Just saw this thanks to your contribution on TheRetroWeb I actually just want to add some detail about the missing parts of this board. The big empty pad near the PCI slots is very likely the famed OPTi 82C822 VLB to PCI bridge chip. Screenshot_20220607_201853.jpeg OPTi 82C822.png So if you ever …

Catsay touts himself as a infallible force and him and a few others continually discourage me from even trying all the time on discord. I do not, but you keep blaming others, and then coming right back to that discord asking for basic input and then again dismissing the details. Yet on several …

This is exactly what you keep doing, every single time. Once again we tell you the flaws and how to improve them, but again for the manyeth time you say "0xCats and others are at fault", "Sphere is the Victim here". And again I get the exact same response. I give up on you.

I don’t have any socket 3 hardware to test this on, and am kinda new to pcb design but I’m willing to try and help if I can. Can you guys describe in detail tweaks and mods that can be done to this socket and make some diagrams and schematics of what is needed? Anyone able to confirm this pin …
Re: Tillamook SMP and multiplier unlocking investigation thread.

Of note also is the issue that the Tillamook CPU's where largely first manufactured for the TCP320 thin film carrier package on which the private bus signals are absent. These where then also packaged into the PGA carrier form. As such the actual connection to the die for the private bus signals is …

Yes they are totally non functional on the the processors I've tested. They also don't output the correct expected signals on PBGNT, PBREQ, PHIT, PHITM and and the DPEN doesn't drive the D/P signals appropriately to indicate dual processor or active processor mode. The pins are just floating or High …

So as someone currently in the process of designing a dual socket motherboard and intimately familiar with the Pentium design I have been asked to add some details here. When Intel went about designing the Tillamook processor they where not developing the next great Pentium CPU, it was developed in …

For a headless build I'm currently working on, I did not want to leave the bandwidth of the AGP port unused. But when looking for information online about using the AGP port for anything else than a graphics card you won't find much, except between the lines of this thread maybe. In most other …
