You mean Triton-II supports parity, and they're calling it ECC, or Triton-II supports ECC, and you're calling ECC parity? The latter is arguably incorrect, and is certainly incorrect in common usage. ECC setups usually use 39-bit stores for 32-bit words and Gray coding (or a variation theron) to provide single-bit correction and double- bit error detection. > Nate -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
