Well working backwards from my most current. Pre-unibody (Sept '08) MacBook Pro 15.4" matte screen with 4GB crucial RAM 200GB 7200rpm, a Marathon PowerRack G3 400 Mhz studio rackmount (genuine mac components in a Marathon case with noisy fans) 256MB OSX 10.3.4 and a Mac PowerBook G3 Lombard Bronze 333 Mhz 192MB running OSX 10.3.4 and system 9.2 which I'll be using to link with and file transfer Bernoulli drive data from a Mac Quadra 900 (graphic design set-up) running system 7.something (I'm going to be upgrading it to system 8.1) at an acoustics firm who resolutely blanked the Mac!
