That&#x27;s a very interesting idea. The smallest real Smalltalk I&#x27;ve seen ran on the 286 in protected mode. It&#x27;s the only app I&#x27;ve ever seen that actually used segmentation usefully --- each object had its own segment descriptor, so it was limited to about 32768 objects. That&#x27;s still way more than will fit in an MSP430.<p>[Aside: I wish they made MSP430s with more RAM. It&#x27;s a lovely architecture, and I&#x27;m not just saying that because I&#x27;m sick and twisted and like devices with 20-bit registers. An MSP430 with a whole megabyte of RAM would be awesome.]<p>I do know of Timothy Budd&#x27;s Little Smalltalk, which is an ultra-lightweight pedagogical Smalltalkish, which has a core image of ~90kB and 3500 objects; but that&#x27;s still rather big...
