Very cool. Does anyone know the model number(s) of gen 1 Galileo? For example, it appears that this one here is gen 1, but I am not sure if it has firmware 1.0.2 specifically: http://www.amazon.co...s=intel galileo

I had to upgrade the firmware on mine. Took about 5-10 minutes to do that and was simple enough. The links posted have the instructions.
Interestingly, in "Windows" mode it's not really too fast. Fastest signal I have been able to get out of the beast so far is ~60Hz with a 33% duty cycle when just toggling GPIO pins.
With a 1ms sleep toggling pin 13 you will get anywhere from 4ms to 14ms on the scope.
This appears to be due to the fact the io is being driven thru a I2C chip.
There are 3 pins driven directly via the quack that result at around 3ms
The same test with netmf running 4.3 on a stm32f427 results at a constant 1.05ms
So that would be a problem for Windows and Linux then? As in a hardware limitation?
I'm really starting to get the impression none of these devices are going to satisfy the needs from a hardware standpoint. If you want to play in the IoT space you better have a SMC soldering pencil ready (metaphorically).
After a week of trying to make it work, I'm going to the FPGA board now.
It seems like the Galileo Gen 2 addresses some of the problems with speed on the I/O pins. I am going to pick one up and see what it can do. Microsoft is also working on a windows OS update for it. Based on your observations on how slow Gen 1 is, I will skip playing around with it.
