Sure, you can do that.
As for the Macs…it worked fine in every G4 made. So, pick the fastest one you’ve got and either put two drives in it or partition the system disk to get started.
Both v7.5.1 and v8.2.3a use the same firmware (03.18.2002), so both versions on two different startup disks can use the same card.
On the OSX side:
-Media 100 i topped out at v8.2.3a (released March of 2006)
-The lastest OS we officially tested with was v10.4.5 (released in February of 2006). However, anecdotal evidence suggests that you can go all the way to OS 10.4.11.
-It was only officially tested up to QuickTime 7.0.4 (released in January of 2006). It’s possible that later versions are okay too but there’s less info out there about this (probably because most people are more in tune with their OS version than their QuickTime version).
***WHATEVER YOU DO WITH QUICKTIME, DO NOT UPDATE TO QUICKTIME 7.5.5, IT EFFECTIVELY “BREAKS” THE MEDIA 100 i CODEC***
Setting up the OS 9 side is a bit simpler:
– Install OS 9.anything and keep running software update till the OS tops out at v9.2.2 and it doesn’t offer you any more updates.
– Media 100 i v7.5.1 is the last version that works on OS 9.
– The last OS 9 version of Boris Graffiti was v2.1.1.
