I'm building myself a new computer with 4gb of ram.  The only way to use 4gb of ram I must install Vista 64.  Is it possible to use Mach3 with Vista 64.  I really don't want to have dual OS but I'd love to use Mach3 instead of getting another software.

I don't believe Mach will run in 64bit Vista, but what other alternative software does?

Are you sure that it won't work in WoW mode 32bit emulator?

nope ,only 32 bit. i think the latest release of vista 32 supports more than  3 gig. you will have to check it out.

I have Laptop Celeron 1200mhz with XP and 512mb of ram.  I heard there is a problem between laptop port and Mach3 so what is the problem?  Can I use Laptop safely?

With a laptop, the only way to know for sure is to install Mach3 and try it.

Is the status of mach and 16 bit going to change in the near or distant future

[u]WILL THIS SYSTEM WORK WITH MACH 3 OR DID I JUST LOOSE A GRAND?[/u]

I've just built a Vista-64bit machine; I will attempt to use Mach3 in compatibility 32-bit compatibility mode.  Any tips/solutions will be appreciated.
