First post. Senior Mac user - since March '84. I still have my original 128k - expanded to a 4 meg "monster" - because I just can't bear to part with it. One of that relatively small group of engineers who use a Mac.
My current system setup: beige G3 rev1 mini-tower with 320 meg of physical ram, 6 meg of vram, the AV package, a two-port usb mounted in one of the pci slots, two hard drives - one scsi 9 gig which I use as the normal startup (95% of the time) and an ATA 80 gig with three partitions. I select one of the ATA partitions as the startup if I want to use my 3D cad program (with a set of extensions that allows it to behave nicer). All of my drives/partitions are formatted as HFS+. But I'm getting anxious to install OSX on my G3 because there are some UNIX programs I want to play with. (I appreciated the discussion of a few weeks ago on that topic.) However, I have one application - absolutely required - which must run on system 9.1 or earlier. Believe it or not, Claris Cad still works pretty well on 9.1. Yep, I know about the other cad programs and nope, for 2D drawing, nothing measures up. And, as most of my actual work these days is in the area of specialty Filemaker Pro development (www.notesoft.com), I'm very hesitant to risk new instabilities. As a user who started with the first Mac system, upgraded many times, and had to back up a few, my caution is based on experience. So, my basic question is, can I leave the 9 meg scsi drive as a system 9.1 setup and install Jaguar on one of the ATA drive partitions without conflicts. When running under OS-X, can you see files on an OS-9 drive? When running OS-9, can you see files on an OS-X drive? Is the HD drive formatting different in OS-X than in OS-9? Would I have to reformat the ATA? Thanks for wading through this and for any responses. If anyone ever needs to know the soft interrupt key sequence for the first Mac system, or how to use the original program switcher, I'll be able to chime in with the help.
