Likewise. And on a related subject, FreeBSD dropped its Alpha support (from the development branch) earlier this week - it had fallen below critical mass - and a lot of this would have been the death of the underlying chip. >From it's start I was very impressed with it.

I can't think of any other architecture where the designers considered what they needed to do to make the architecture future-proof. The normal architectural design criteria are a mixture of the number of transistors they can fit on a chip today and backward compatibility. >so presumably OSF1/Digital UNIX/Tru64 is either dead or end-of-lifed as It's effectively end-of-life.

If Linux and *BSD aren't Unix, how do you define Unix? (Other than having paid TOG the trademark licensing fees). >PowerPC, and VAX.

There's a bit of a feedback loop: Starting with the IBM-PC, x86 sold in large volumes, so there were lots of profits and design costs could be amortised over a larger volume, allowing more man-hours to be invested in the next generation whilst still returning a profit. This makes the next generation of x86 outperform the competition at a lower price - encouraging more people to use x86. >While IA-64 is based on the PA-RISC, it's still Intel, I suspect the IA-64 will quietly fade away. It hasn't lived up to the hype and even Intel seem to acknowledge this by licensing the amd64. >and lots of RAM (the fastest machine SunOS 4.1.4 could run on -- and >I've heard that 4.1.4 did have very alpha SMP support, similar to what SMP support started earlier than 4.1.4. The sun4m machines (SS470, SS670) were the first SMP machines and ISTR they were supported in the last 4.0.x or early 4.1.x releases. (I was using them at the time but the details have faded a bit after 15 years). >Linux and the modern BSDs used for a long time, that being a "big giant >lock" [mutex] around the kernel). Most early SMP systems worked this way - it's relatively easy to implement and gives good CPU utilisation on CPU-intensive tasks (that don't need the kernel much). -- Peter Jeremy
