don't quite seem to go together.

The enitire layout of the OMS looks a lot more like a PRISM to me than the PRISM to a MK15 ... maybe just an optical illusion.

To me, as an engineer, I don't even see things like the physical layout as significant. I'm looking at deeper architectural design features. The Mark-15 v/s Prism electroncs design architecture is identical (and the Prism's pod was originally tested on CCR-1000 platform, which I happen to *own*, remember?). Direct reading secondary. The use of untimed solenoid injection to dump a bolus of 02 from an accumulator with upstream flow restrictor to control accumulator filling rate is identical. The pneumatic diagram is *identical*. Those are the architectural features that I see. I don't see the scrubber and counterlung designs to be anything other than design details.
Here's an example: The Prism and the Meg look a lot like each other. They have zero similarities. They look like each other because the "optical illusion" is dominated by the CL design and the scrubber placement. The Prism and the Mark-15 look *completely* different, but they share a virtually identical design architecure from a gas flow and electronics standpoint.
The rig is not, BTW, an OMS rig. OMS hosted the rig in it's booth.
