What operating systems does it run on?
IBM-PCs and compatibles running MSDOS (which includes MS-Windows, DR-DOS, Novell DOS, and OS/2 if you have enough memory). Many variants of unix. In particular, configuration options are already in place for: NeXT, BSD 4.2/4.3, A/UX, SUN, LINUX, IRIS, Ultrix, XENIX, Interactive 386/ix, HP/UX, Altos 2000. If you have one of these environments, Waffle should just drop in with no problems.
