        Sun-3 Models
        ------------

    3/160
        Processor(s):   68020 @ 16.67MHz, 68881, Sun-3 MMU, 8 hardware
                        contexts, 2 MIPS
        CPU:            501-1074/1096/1163/1164/1208
        Chassis type:   deskside
        Bus:            VME, 12 slots
        Memory:         16M physical (documented), 256M virtual, 270ns cycle
        Notes:          First 68020-based Sun machine. Uses the 3004
                        "Carrera" CPU, which is used in most other Sun
                        3/1xx models and the 3/75. Sun supplied 4M
                        memory expansion boards; third parties had up to
                        32M on one card. SCSI optional. One variant of
                        the memory card holds a 6U VME SCSI board; there
                        is also a SCSI board which sits in slot 7 of the
                        backplane and runs the SCSI bus out the back of
                        the backplane to the internal disk/tape (slot 6
                        in very early backplanes). CPU has two serial
                        ports, Ethernet, keyboard. Type 3 keyboard plugs
                        into the CPU; Sun-3 mouse plugs into the
                        keyboard. Upgradeable to a 3/260 by replacing
                        CPU and memory boards.

    3/75
        Processor(s):   68020 @ 16.67MHz, 68881, Sun-3 MMU, 8 hardware

                        3/280 by replacing the CPU and memory boards.
                        Very early backplanes have the special SCSI
                        hookup on slot 6 rather than 7.

        Bus:            VME, 3 slots
        Notes:          Similar to the "Carerra" CPU, but has 8-bit
                        color framebuffer (cgfour) on board and uses 1M
                        RAM chips for 4M on-CPU memory. Code-named

        Bus:            none
        Memory:         4M physical (documented), 256M virtual, 270ns cycle
        Notes:          Cycle-stealing monochrome frame buffer. 4M
                        memory maximum stock, but third-party memory
                        expansion boards were sold, allowing up to at
                        least 12M. No bus or P4 connector. Onboard SCSI.
                        Thin coax or AUI Ethernet. Code-named "Model
