Was there a 16-bit version of Mindstorms?

RCX and Micro/Scout used 8-bit CPUs. NXT had a 32-bit CPU. Was there ever a 16-bit version? I'm just curious.

Hmm - define 8-bit ;)

The Hitachi/Renesas H8/300 microcontroller built into the RCX has eight 16-bit GP registers it uses for various things ...

But yes, as the Zilog Z80 CPU, the H8/300 used in the RCX is considered an 8-bit microcontroller (8-bit data handling).

I don't think there was any true 16-bit microcontroller used in LEGO PBricks - the time between release of the RCX and the NXT was so long, that it did nor make sense to use a 16 -bit variety but do it right away with a 32-bit (RISC) controller.  

Best,

That's what I figured.
