    processor
  • PowerPC 604e @ 150 / 180 / 200 / 233 MHz
  • 68040 @ 25 MHz or 68060 @ 50 MHz
    • can be ordered without a 680x0 companion CPU to put an existing one into the socket
    memory
  • four 72 pin SIMM sockets accept 128 MB RAM
  • supports 4, 8, 16, 32 MB SIMMs 60-70 ns
  • 64 bit interleaved RAM access
  • the Cyberstorm PPC is a bit picky about DRAM Chip Memory Array organization
    • the card only has 11 address lines, thus only 2048×2048 organized DRAM Memory Arrays are supported
    • 1024×4096 organized chips would need 12 address lines and are not working
    • the Memory Array organization is given in the chip datasheet and not to be confused with the output bit configuration (e.g. 4M×4) of a DRAM chip
    • if the chip has the wrong organization, only half of the RAM is recognised
    notes
  • NCR 53C770 Ultra Wide SCSI controller - follows the Wide Fast 20 standard, supported by NetBSD
  • expansion slot for the CyberVision PPC
  • the SCSI controller needs the INT2 signal which is not present in the A3000's CPU slot
