    MEMORY

  • memory on board the CPU is 8MB
  • the minimum memory is 16MB (parity)
  • 56MB of memory is available on a
  • available in 8MB increments
  • the memory board goes in slot 3 and will
  • have a max of 48MB on board
  • the 390 uses parity memory for cost saving
  • the reason it has a limit of 56MB is the
  • memory controller can not support
  • more than 56MB
  • for more details on memory error recovery
  • search for memrecover

    MONITOR

  • optional; 19" monochrome; 19" color

    PACKAGE

  • 56" 16 slot cabinet; 4GB, (2) 5 1/4" devices & 1/2"

    PROCESSOR

  • Cypress CY7C601, 25 MHz
  • 25Mhz; same as 330/370

    FPU

  • FPU is TI8847; 25Mhz; 2.7 Megaflops

    MMU

  • supports 16 contexts in memory 1 GB each

    CACHE

  • cpu has 128KB write-through cache
  • the 390 does not have an I/O cache because
  • w/IPI controllers it achieves very high performance

    PERIPHERALS

  • 1/4" tape, disks, 1/2" tape

    PORTS

  • 4 rs232/423 ports on cpu board
  • up to four 16 channel ALM-4s for 64 ports

    TAPE

  • tape is 150MB SCSI 1/4" tape
  • optional Front Load 6250/1600 HP tape drive
  • the HP can stream a 135MB partition in 5 minutes
  • the max 1/2" tape drives is 3, up to two
  • bin one expansion cabinet. One FL tape
  • takes up the same space as 4 IPI's

    DISK

  • 32 GB of Disk capacity
  • 4GB (4 IPI's) can be put in the bottom of the
  • main cabinet
  • each expansion rack can have up to 16GB
  • there is max of two expansion racks
  • the absolute max is 32 drives on the 390
  • this means that if you have 4 disks in your
  • CPU enclosure you can only have a total of 28
  • drives in your expansion racks

    SCSI

  • 4.8 MB/sec synchronouse SCSI Bus
  • slots for up to 2 full height 5 1/4" devices

    IPI2/DC

  • IPI-2 drives transfer rate 3MB/sec;
  • 1 controller handles 8 drives at once
  • multi-threaded cache supports several users and
  • tasks simultaneously; uses RPS

    BUS

  • 16-slot VME data center rack
  • 2 - 5 1/2" devices 1/2" tape in a single CPU enclosure
  • each expansion rack can have up to 16GB
  • there is max of two expansion racks

    OPERATING SYSTEM

  • 4.0.x and higher

    POWER

  • power supply is 200-240VAC, 925 watt auto-ranging

    DBA

  • < 55 dba for CPU and < 65 dba for expansion rack

    SERVER

  • up to 68 users; 15-30 diskless clients

    UPGRADE

  • upgradable to a 490

    NOTE

  • DISCONTINUED as of December 14, 1990
