[time-nuts] Low cost GPS module for < 100ns timestamping error

[Chris Albertson]

Looks like this is all you'd need for most timing projects.  Just add your
favorite OCXO and some wire.

The SPARC (not Spark) is actually a step up from ARM.  It was developed by
Sun Microsystems (now Oracle) it is optimized for things like fast context
switching, multi tasking and so on, all the things done by operating
systems. The Sparc V8 does 128 bit floating point, (quad precision) I
wonder if 200Kb RAM is enough to run an older version of SunOS?  (a BSD
variant.)

Are these shipping yet?
