Track Bandwidth Use with VirusBarrier X6

If you have monthly bandwidth limits, it's useful to know how much data you have used so far to avoid overage charges or being shut off by your ISP. But how do you determine how much data your Mac has transferred? Open VirusBarrier X6's Traffic window to see both current and cumulative traffic, and you can also create warnings when your data usage - incoming, outgoing, or both - exceeds an amount you specify.

IIvx & A/UX

Send Article to a Friend

In an effort to clarify Mark's article on the incompatibility between the IIvx and Apple's Unix operating system, A/UX 3.0 (TidBITS-157), Pythaeus writes:

The Mac IIvx does not run A/UX 3.0 for the same reason that System 6 does not run on the Quadra 700: the CPU was released long after the system software shipped, so the operating system (OS) can't possibly know about the addresses and capabilities of the new hardware. A/UX 3.0 does such a good job of making Unix look like a Macintosh that people forget the operating system is Unix, not MacOS. A/UX does not sit on top of System 7 (a la Tenon), but the other way around. It makes no sense to talk about A/UX being "System 7.1 compatible" once you understand this fact. Unless the hardware designers bend over backwards to maintain compatibility, you will always need a new OS (or new OS components) to support new hardware. The Mac IIvx was released after A/UX 3.0, and contains new ASICs (like its sound chip), so A/UX 3.0 has no clue what to do.
