Hi guys I am brand new to the SX chip I bought a kit from gadget gangster great company anyway I built the kit and everything seems to work but is there a way I can program this chip
without buying that adapter???? is there just a simple way to connect it to RS-232?? if not is there a kit or project anyone has schematics for that I can build myself.
thanks guys

It's not like the Basic Stamp where you can simply connect it to the serial port. The chip is programmed through the oscillator pins, and requires a special protocol to access the flash inside it to load the program. That's what the SX-Key is for.
The protocol is documented: http://www.parallax.com/Portals/0/Downloads/docs/prod/sx/DeviceProgramming.pdf
The SX-Key is not that expensive - and remember, you can use that one key to program as many SX chips as you like.
Make sure you read up things like Programming the SX Microcontroller: A Complete Guide by Gunther Daubach, the SX-Key Development System Manual by Parallax, Inc. (http://www.parallax.com/Portals/0/Downloads/docs/prod/sx/SXKeyMan2_0.pdf) and others.
Lots of source code, documentation, software for the SX here: http://www.parallax.com/ProductInfo/Microcontrollers/SXProductDownloads/tabid/460/Default.aspx
Good luck!
