When I got my first 3dfx card at that time I took a bit of time to look up PCI ports specifications to see if there was a bit of hope of using it on the Amiga. This never went past the preliminary research stage though, playing Quake on the PC and testing Samuel Devulder's version on the 1200 took too much time.
Sorry for the off-topic!
(Not even sure anymore if this was PCI actually.
