CDi2.P6 Prototype
  • Newer hardware platform based on the Zilog s180 meant to eventually replace its PDL divine predecessors.
  • Development started early in 2000, on Adam's own time... had to sell a million beers to support the R&D, really, really, and continued strongly until 2004 or so. It was never implemented as a CDi/PDL in the lake because the pressure transducer/transmitter technology of the day didn't deserve it. Adjust this, calibrate that, why bother? Some consideration was given to the HART bandwaggon but no benefit to the lake operation was identified.
  • So little CDi2.P6 was put on the back burner, until the Keller discovery. It has since become the CDi3.P7, all-digital Lake Erie workhorse.
