Programming old Innovation FIRST boards

[Sconrad]

A mentor on my team wanted to know if we could set up an old robot (2001) to run again. He told me that the hardware is still fully operational, but it needs code. I told him I would look into it, but can't figure out the tools I would need. I had not heard of FIRST until long after we switched to the cRIOs and have very little idea where to start other than C++ so any information is appreciated. Some specific questions I have are:

Is this even remotely possible?

Does the board need to be imaged like the cRIO? If so, how would I go about doing that?

Would using the new C++ WPILib code not work on the board, or is it backwards-compatible? Will the Windriver software be supported?

It isn't like this project is of any urgency, but I would be interested to see whether it's possible and how it is done. Thanks for the feedback!
