The MSP432 is an ARM based line, whose name resembles the older 16-bit MSP430 line, presumably to call attention to its low-power emphasis. The MSP432 launchpad is a nice little board for $12.99 USD http://www.ti.com/tool/msp-exp432p401r A 48 mhz Cortex M4F with 256k flash, 64k ram, 24 channel adc and other i/o galore, all supposedly running at 80 uA/Mhz. Impressive. I agree with Stephen that Dale will likely have an easier time with MPEforth than Mecrisp, and I'm sympathetic to "Translates to: we'll pay for hardware but not for software." In reality though, the software is an OOM more expensive than the hardware so there's a higher entry barrier.
