the NXT has 64KB RAM and 256KB flash, of which we will have to leave some to the ROM. My optimistic guess would be that we get ~60KB RAM and ~200KB flash to play with. So squawk (and all other VMs I've looked at) exceed this a bit. The open source VM closest to fitting in NXT IMHO was JamVM, Squawk would be second but is probably not open source (?). It has some interesting concepts to write most of the OS in Java, with special instructions in the VM to support e.g. thread switching. For a start I'd rather stay close to what we have in Lejos and port that to NXT. This will most likely be the easiest and quickest way to get Java running on the NXT, and we can then incrementally extend it to make the most of NXT.
