        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
                        contexts, 2 MIPS
        CPU:            501-1074/1094/1163/1164
        Chassis type:   wide pizza box
        Bus:            VME, 2 slot
        Memory:         16M physical (documented), 256M virtual, 270ns cycle
        Notes:          Optional SCSI sits on memory expansion board in
                        second slot.

    3/140
        Processor(s):   68020 @ 16.67MHz, 68881, Sun-3 MMU, 8 hardware

        CPU:            501-1074/1094/1163/1164/1208
        Chassis type:   deskside
        Bus:            VME, 3 slots
        Memory:         16M physical (documented), 256M virtual, 270ns cycle

    3/150
        Processor(s):   68020 @ 16.67MHz, 68881, Sun-3 MMU, 8 hardware
                        contexts, 2 MIPS
        CPU:            501-1074/1094/1163/1164/1208
        Chassis type:   deskside
        Bus:            VME, 6 slots
        Memory:         16M physical (documented), 256M virtual, 270ns cycle

    3/180
        Processor(s):   68020 @ 16.67MHz, 68881, Sun-3 MMU, 8 hardware
                        contexts, 2 MIPS
        CPU:            501-1074/1094/1163/1164/1208
        Chassis type:   rackmount
        Bus:            VME, 12 slots
        Memory:         16M physical (documented), 256M virtual, 270ns cycle
        Notes:          Rackmount version of 3/160. Upgradeable to a
                        3/280 by replacing the CPU and memory boards.
                        Very early backplanes have the special SCSI
                        hookup on slot 6 rather than 7.

    3/110
        Processor(s):   68020

        Chassis type:   deskside
        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
                        "Prism".

        Processor(s):   68020 @ 15.7MHz, 68881 (socket for
                        501-1075/1133/1162, installed for 501-1207),
                        Sun-3 MMU, 8 hardware contexts, 1.5 MIPS
        CPU:            501-1075/1133/1162/1207
        Chassis type:   wide pizza box
        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
                        25".

        Chassis type:   wide pizza box
        Bus:            P4 connector (not same as P4 on 3/80)
        Memory:         24M physical, 256M virtual, 200ns cycle
        Notes:          VRAM monochome frame buffer for 501-1205/1334.
                        Optional color frame buffer (can run mono and
                        color simultaneously) on P4 connector. Onboard
                        SCSI. SIMM memory (100ns 1M x 9 SIMMs). High
                        (1600 * 1100) or low (1152 * 900) resolution
                        mono selectable by jumper. Thin coax or AUI
                        Ethernet. Code-named "Ferrari". 4M stock on

        CPU:            501-1378
        Bus:            P4 connector (not same as P4 on 3/80)
        Memory:         12M physical, 256M virtual, 200ns cycle
        Notes:          A version of the 3/60 with no onboard

        Notes:          Two serial ports, AUI Ethernet, keyboard, and
                        video on CPU. Video is mono, high-resolution
                        only. Sun supplied 8M memory boards. Sun 4/2xx
                        32M boards work up to 128M. First Sun with an
                        off-chip cache. Upgradeable to a 4/260 by

                        virtually-indexed and virtually-tagged, with
                        16-byte lines; 80ns cycle
        Notes:          Rackmount version of the 3/260. Upgradeable to a
                        4/280 by replacing the CPU board. Code-named
                        "Sirius".

                        (720K on early units?). No onboard framebuffer.
                        Code-named "Hydra". Type-4 keyboard and Sun-4
                        mouse, plugged together and into the machine

                        same memory boards as 3/2xx.

        CPU:            501-1299/1550
        Chassis type:   rackmount
