I got the Parallax Propeller Demo Board (rev D) this last week. This is a Propeller uC on a small (3" sq) board with many auxilary components (EEPROM, I/O, power regulators, mini breadboard blocks, LEDs) already mounted on the PCB. Amazing stuff. It can drive a VGA and NTSC (both at once, if you like) using (on-board) resistors and some programming in order to construct a simple DAC. It takes input from PS/2 keyboard and mouse. It has sound. And the board has a USB to RS232 converter so I can hook up to it directly with USB for programming.
Actually, I'm a little stunned at the moment - there are so many possibilities for fun projects that I don't even know where to start. I've been playing with the DIP version of the Propeller for a while on a breadboard, and have some of the programming down ("Spin" language). There are lots of fun sample projects and modules to try from the Parallax download section and the forums. But one of my main goals is to build a virtual disk drive for a particular retrocomputer, so I'd better get to it.
8 of the 32 I/O pins are not used for onboard connectors and come out to a breadboard header - more than enough for my purposes. 2 for the serial I/O, and some others (2? 3?) for connecting to a pre-built SD card reader unit (this will store the virtual disk images for the drive simulator).
