Hey ken and you software wizards at parallax.

How about this for a rocket stamp?

A javelin hardware base with sx/sxb software to allow the whole 32k x 32k to be used in sx/sxb programs.

This would allow large programs and also allow extensions of the core process to be added in the field. I.e.
Machine language uarts, interupt handeling and other blast off capabilities that are currently unsupported or impossible with the small memory devices.

32 kbytes of eeprom and 32 kbytes of ram is about equivelent of the old trs-80 model 4 or 2, and that was no slouch. Also this would be about 1/5000th of the size of those machines. How about stuffing 10 or so virtual perifrials under that little shell?

Seems to me this could be star trek 2010 for stamps.

Blast off!!!!!!!!!!!!!!!!!!!!!!!!!!

    SPENCE,
    THE SX DOES NOT HAVE THE ABILITY TO RUN CODE FROM EXTERNAL MEMORY.
    GREAT IDEA THOUGH...

    My understanding ofthe javelin is that it moves the code to where it needs it.

    The Javelin uses an interpreter kind of in the way the BASIC Stamp does -- the difference, of course, is that it executes Jave bytecodes instead of PBASIC bytecodes. The Javelin moves the bytecodes from EEPROM to RAM because pulling the bytecodes from RAM while executing a program is faster than doing it from EEPROM. To Bean's point, it is NOT running assembly code except inside its own core (JVM).

    Wouldn't Spence's idea be about the euivalent of making a SX48 Con Carne that was pin compatible with the 24 pin stamps?
