OK. About 3 years ago I came around with the thought of trying to run newer CPUs on an older P3-Boards. Sadly It turned out not to be possible.
Introduction and CPU Adapter Idea
The last days I was searching around the internet for quad-cpu boards of that era and could not find one
Then I remembered my analysis from this older idea and the fact that the p3 FSB is a purely passive bus and all CPUs run parallel on it.
The only important signals are the bp0/1 that get twisted from one cpu to the next and manage which one can access the bus.
I've read about these signals from talks about slotket adapters, some are smp-capable and some are not.
Idea: Build a slot1-pcb that hold 2 cpus!
I'd take upga ones, they are smaller and have a lower power consumption (the onboard dc/dc converter must supply both)
And if you have a dual slot1 board like my asus p2b-ds you can equip it with a second board, making it a quad-cpu system
But why stop there? Maybe a quad-slot1 pcb is possible too resulting in a octa system.
I don't know the limit for the cpu count on the p3-fsb and for this it would need a dedicated power converter.
Is that idea too crazy or not?
