I had one.  It was a bit of a gimmick beyond "I need a really portable
SPARC machine"; I did know a couple of sales reps who carried one for demos
when the Tadpoles cost about twice as much for far less horsepower (up to
Ross HyperSPARC @ 180MHz v TI 50MHz microSPARC).  It was more like a SS20
cut down to 1 MBus and 1 SBus slot.  I recall it was kinda finicky about
which MBus processors it liked beyond the Ross Hypersparcs, and had a bad
heat problem (which I suspect is what eventually killed mine).
