When the IT Dept gets rid of computers they either trash the hard drive and throw them away or give them to a recycling computer company to hipe the HD and resell them.  You should look into it.

I have found some amazing deals with off-lease computers.  Ubuntu, Linux Mint or another easy *nix might be suitable for you for these purposes.   :)

Thanks for the idea on using #define for constants... I should have known better. :P

I'll post the updates soon.  Never know when you need to know how much your butt weighs on the Moon!  or Uranus...   :P
