[time-nuts] Thunderbolt Monitor

[Bob Camp]

Hi

I do believe I included the size of the DOS exe as well as the Windows
version. Both get *some* support from the OS that you will need to implement
in your code. 

It's not just program space either. You only have 512 bytes of RAM on the
larger of the two processors.

You can't compare the size of a Windows binary to a uP RAM.   If you
look inside the .exe file you see that 90% of it is dealing with the
Windows OS.   The actual computations are very, very small and don't
use even half the 16KB Flash.
