    processor
  • 68040 @ 28 / 33 / 40 MHz
    • the board was available with an empty CPU socket to put an existing 25 MHz 68040 into it
    • the 28 MHz 68040 is an overclocked 25 MHz one
    memory
  • A4000: four 72 pin SIMM sockets accepts up to 128 MB RAM
  • A3000: two 72 pin SIMM sockets accept up to 64 MB RAM
  • supports 4, 8, 16, 32 MB, 60-80 ns SIMMs
    • 40 MHz version needs 60 ns SIMMs
    • 33 MHZ needs 70 ns
    • 28 MHz needs 80 ns
  • full 040 burst memory access (4/2/2/2 clock cycles - 64 MB/s memory bandwidth)
  • configuration
    • wait-state jumpers for slow SIMMs
    • jumpers for setting the size of the biggest SIMM
    • jumpers for double-sided SIMMs
    Fast SCSI 2 controller
  • NCR 53C710 @ 40 MHz
  • 32 bit SCSI host bus DMA interface supporting burst to/from RAM
  • max 10 MB/s synchronous transfer speed
  • autoboot ROM (warpdrive.device) - can be disabled by a jumper
  • incompatible with the A3000's motherboard SCSI controller - replacing the A3000's SCSI chip to rev. 08 solves the problem
  • external SCSI connector is only available separately
  • supported by Linux, NetBSD and OpenBSD
    notes
  • cannot maprom
  • MMU and cache disable jumpers
    A3000 notes
  • not expected to work with static column RAM on the motherboard
  • can provide 25 MHz clock signal to the motherboard (useful for a 16 MHz A3000 system)
