NetBSD/sparc 1.0 runs on Sun4c class machines only, which includes the SS1, SS1+, SS2, IPC, ELC, IPX, and the SLC. It does not run on Sun4, Sun4m, or Sun4d machines. The minimal configuration requires 4M of RAM and ~60M of disk space. To install the entire system requires much more disk space, and to run X or compile the system, more RAM is recommended. (NetBSD with 4M of RAM feels like Solaris with 4M of RAM.) Note that until you have around 16M of RAM, getting more RAM is more important than getting a faster CPU.) Supported devices include: Video: cgthree, cgsix, and bwtwo frame buffers Serial ports: ttya and ttyb On-board AMD Lance ethernet Some SCSI CD-ROM drives Sun keyboard and mouse Hardware the we do NOT currently support, but get many questions about: The floppy drive. The next release will likely run on many more machines. In particular, some Sun4 support will be there, and perhaps even Sun4m.
