Specware has relatively modest system requirements for simple projects. Of course, as with any development tool, as your projects being developed become more complex, you may wish to work on a more powerful machine. For average use, however, the following basic hardware configuration is recommended:
CPU: 250 Mhz
RAM: 128 MB total, at least 64 MB free for applications
Disk space: 15 MB for base system, 10-50 MB for user projects
