Something that hasn't been done which I would absolutely love is an AGP switcher. Imagine having multiple AGP cards in one computer that you can select with some sort of hardware switch before booting. Then you can boot into a hardware profile to match. For my Windows 98 games, this would be so cool.

Physical space apart, this seems quite simple. Put multiple AGP ports with all lanes but the power suppy in parallel. Then switch only the power to the desired slot.

AGP just like PCI (as thats what it started as) uses reflected-wave switching. Afaik cant just parallel few connectors and call it done at those frequencies, even 66 MHz PCI (AGP x1 speed) was pushing it and PCI-X requires PLLs and controlling delays. https://electronics.stackexchange.com/questio … -captured-by-th

Sounds like that would be best approach to develop it, get a PCI 66 board/backplane and do it in AGP 1x first....

... though for "plenty of space" just have 4 boards with KVM.

It is probably possible to figure out a goldilocks config with one of those AGP/PCIe boards where you have older GPU on a PCI32 slot, or two of them, GPU in AGP, and a PCIe bridged late period "AGP" available one on the PCIe.

A new motherboard for Sony Vaio P gen2 with modern specs would be amazing. Or new drivers for the GMA500.
