That's a very interesting idea. The smallest real Smalltalk I've seen ran on the 286 in protected mode. It's the only app I've ever seen that actually used segmentation usefully --- each object had its own segment descriptor, so it was limited to about 32768 objects. That's still way more than will fit in an MSP430. [Aside: I wish they made MSP430s with more RAM. It's a lovely architecture, and I'm not just saying that because I'm sick and twisted and like devices with 20-bit registers. An MSP430 with a whole megabyte of RAM would be awesome.] I do know of Timothy Budd's Little Smalltalk, which is an ultra-lightweight pedagogical Smalltalkish, which has a core image of ~90kB and 3500 objects; but that's still rather big...
