    processor
  • 68040 @ 40 MHz or 68060 @ 50 MHz
    • the 68040s are recycled from used Macs
    • the board is ready for 68060 @ 66 MHz
    memory
  • four 72 pin SIMM sockets can accept 128 MB RAM
  • supports 4, 8, 16, 32 MB SIMMs, 70 ns
  • onboard logic maps any combinations of SIMMs into one contiguous block without the need of jumpers
  • burst mode RAM access
  • improved access to chip RAM using a write buffer
  • RAM access is 70 ns even with 60 ns SIMMs
    optional Fast SCSI 2 module - CyberSCSI Mk2
  • does not fit mechanically into a desktop A3000
  • 32 bit DMA engine - FAS216
  • max 10 MB/s transfer speed
  • 50 pin internal header
  • autoboot capability
  • requires the INT2 signal which is not present in the A3000's CPU slot
  • the module itself is not equipped with termination resistors; they are placed on a separate PCB which houses the external 50 pin micro-D SCSI connector
  • this automatic resistor finds out on its own whether it is the last piece of equipment on the backbone and switches itself on if this is the case
  • supported by Linux and NetBSD
    Flash ROM
  • contains the updatable CyberStorm firmware
  • needs update for the 66 MHz design
  • needs update for installing the SCSI module
    notes
  • CyberStorm 040 SN# B400506 - B400569 and CyberStorm 060 SN# B002827 - B003065 are affected by several DMA related problems due to a slight difference in the electrical specifications of certain parts caused by supplier change
  • symptoms:
    • SCSI units connected to the internal SCSI bus of the A3000(T) are not recognized while having RAM installed to the CyberStorm
    • does not work in the A4000T with RAM installed on the CyberStorm
    • in an A4000 with a Fastlane or a A4091 SCSI controller installed, peripherals connected to the SCSI bus are not recognized
  • boards with these serial numbers had to be sent back to Phase5 for rework
