rw2 is an ISA card, generating 16-bit hardware random numbers based on the central limit theorem.
The numbers are produced at a speed of more than 16,67 MByte/s and emitted at clock frequency (0..8.33 MHz) as digital noise (sequence of independent random bits, white noise with a critical frequency = 1/4 clock frequency) using a BNC connector. This card is also hot swappable and has also a stereo output (0..2*4.17MHz), three control LEDs (supply voltage, BNC output, clock) and can be used without an ISA-bus because the card does only need 5V and a clock

  • Speed (without overclocking): 16.67 MByte/s (the ISA Bus can only read approx. 2 MByte/s)

  • Power Supply: 5V/0.75A
  • Weight: 250 g
    • Speed (without overclocking): 80 MByte/s (the PCI Bus can only read approx. 5 MByte/s)
    • Dimensions (incl. IBM Bracket): 23 x 12 x 2 cm
    • Weight: 330 g
    • Speed (without overclocking): 160 MByte/s (internal data rate, the PCI Bus can only read approx. 10 MByte/s without DMA)
