Maybe we could get them to port it to Linux ?

Well.... If I could find a drive sled for my DS-20e...

.... I wouldn't be as interested.. There are a limited number of Alphas in the world..
One day emulation will be the only way once everything wears out.. :cry:

hehe, yeah, never liked it really but i'm still curious. got an old oracle book with quite a lot of vms examples and it's one of a few operating systems i never tried.

no, worse than that would be running intel binaries under emulation (and profile/rewrite as Alpha machine code on the fly) on an emulated Alpha.

In the 1990s I did Visual C++ on Alpha and that was painful, running Intel binaries on the Alpha was worse because it would profile your code and rewrite sections of it as Alpha machine code, so your programs were supposed to get faster the more you ran them... but it seemed horribly slow... a pentium 90 was kicking the 200 or 300 MHz Alpha's butt under WindowsNT

At least NT on alpha had some native software, unlike on PPC or MIPS.

Too bad native software for AlphaNT is pretty hard to find nowdays. I remember having versions of Word and Excel, there was also a very fast port of Seamonkey and also a port of Quake2. I should still have most of the stuff I had backed up to a DLT-tape somewhere.

NT on alpha is the fastest version of Windows I have used, and FX32! was actually not that bad.
