(...) There is certainly a huge difference - but given that the NXT has RAM and 'broad-side' Flash on-chip, the bulk of the flash only has to function as backing storage...like a disk drive. (...) You can page executable stuff into RAM as needed. (...) (20 years ago, 13-Jan-06, to lugnet.robotics)

(...) Ah, I missed that one. No need to make a custom chip if they've already got one- and since it has a sufficient amount of ram and flash on board, there isn't much choice. Unless there are similar chips out there with more? (20 years ago, 13-Jan-06, to lugnet.robotics)
