Here you go: http://www.kyllikki.org/hardware/wwwpic2/src/wwwpic2.asm.html http://www.kyllikki.org/hardware/wwwpic2/src/wwwpic2.asm.htm... Bonus: runs on 68 bytes of ram. Not a typo, it's bytes, and it's a "complete" http+tcp/ip server.

Awesome. Can VirtualBox or VMWare run this?

  From the first line of the source, it's a PIC (microcontroller) program, rather than something for x86 (which VirtualBox and friends emulate), so, no. There are a few open source PIC simulators -- e.g. [1] -- and I would guess you might be able to get it running, since the link layer is SLIP over a serial port. You'd just have to wire up the simulator's serial console in the right way. [1] http://gpsim.sourceforge.net/ http://gpsim.sourceforge.net/

That is just running the TCP/IP layer speaking RS232 and relying on an external IC for lower layers. It's not at all what the GP is looking for. It should probably also be noted that a minimum TCP header, with no data attached, is 20 bytes, so to implement a 'full stack' in 68 bytes is a pretty strong indication that you're relying on off SoC memory to handle the packet buffering.

  I encourage you to read the source code instead of guessing how it may work.

Bet that handles TCP fragmentation well :) Nice work though to whoever crammed that in a PIC.
