I checked the site, and I'll save some of you the trouble - here's the system requirements......
PC Systems or Notebooks with Genuine Intel® Pentium® 350MHz or faster processor
Intel® or 100% compatible motherboard chipset
Windows® 98SE, Windows® 2000, Windows® Me or Windows® XP™
64MB system RAM for Windows 98SE. 128MB system RAM for Windows® 2000, Windows® Me or Windows XP™

My laptop is only a 300Mhz, but I am happy with the midi performance as a partner to my psr2k. It was tempting thgough. If you ever see one of the Roland/Edirol PCMCIA Sound Canvas'- scoop it up! That sounded like a winner.
