A current guess is that the ROM is at 0xfefe0000 -- 0xfeffffff
The floppy and parallel port are unique to the 3/80 and are as follows:
controller fdc0 at obio ? csr 0x6e000000 priority 6 vector fdintr 0x5c device pp0 at obio ? csr 0x6f000000 priority 1The 3/80 is called a sun3x "class" machine (the few machines with a 68030) The only other sun3x I know of is the 3/470. The following addresses are for sun3x machines:
device le0 at obio ? csr 0x65002000 priority 3 (lance ethernet) controller sm0 at obio ? csr 0x66000000 priority 2 (scsi) device zs0 at obio ? csr 0x62002000 flags 3 priority 3 (zilog serial) device zs1 at obio ? csr 0x62000000 flags 0x103 priority 3 device cgfour0 at obmem ? csr 0x50300000 priority 4 (cgfour 8-bit framebuffer) device cgsix0 at obmem ? csr 0x50000000 priority 4 (accelerated 8-bit framebuffer) device cgeight0 at obmem ? csr 0x50300000 priority 4 (24 bit frame buffer) device bwtwo0 at obmem ? csr 0x50300000 priority 4 (monochrome frame buffer)Looking at NetBSD 2.0 sources, the file usr/src/sys/arch/sun3/sun3x/obio.h gives:
