My co-worker has given me perhaps the greatest reason to upgrade my Sawtooth G4 beyond playing Sim City 2000, tons of free SCSI stuff. Over the next half year or so, my school's photography lab technician and I are to sort out and dispose of all the old "unusable" equipment. Problem is we can't legally sell any of it, all of it needs to be junked or "donated" to a student. Even though faculty falls into the grey area, I'm still grabbing all the good stuff I can. So now I have to upgrade my old Sawtooth from close to stock to something that can interface with multiple SCSI devices, possibly network with OS X, and run a few other side projects. What I'd like to do with it: Run two SCSI scanners simultaniously Network with a large hard drive inside my Mac Pro Composite video in for recording VHSes (optional and real time preferred) Run dual monitors. 1920 x 1200 DVI and 1680 x 1050 VGA. In the future the smaller monitor may be replaced by a 27 inch Apple Cinema display and the 1920 monitor will be turned 90 degrees. Here's a rundown of the specs: 500 Mhz ATI Rage 16MB 1.25 GB Ram 4x 80GB ATA drives The Apple SCSI PCI Card 4x USB 2.0 Card OS 9 and 10.4 I figure I'll need a much beefier GPU to run two monitors under OS 9 and I'm not even sure if it can run monitors can run 90 degrees. Whats a cheapo card that should be able to work with a 2440p screen? Would it be possible for OS X and 9 to see each other over a network and access each other's drives? Or how about screen sharing, is that possible between 10.9 and OS 9? Since my G4 doesn't have gigabit ethernet, could I network over Firewire? Will the little 500mhz processor be a drag on what I want for it? Will a Digital Audio 733mhz CPU work? How well would a ATA to SATA adapter work for a 64GB SSD for OS 9? What composite In cards were available during the G4's heyday and did any of them allow viewing in real time? Thanks!
