Modifications to existing C Code

Project relates to a series of medical instruments. The code and design go back 30 years.

The original devices boot DOS and run their C code program all on a floppy disk.

In 2011 DOS and the program were modified and moved to run on a 'C' hard drive basis however an 'A' floppy disk was still used for saving of backup/recovery data. We now need this to be changed within the code to save this backup/recovery data to a USB drive instead of the 'A' floppy.

We intend to update the whole device next year and will be looking to rewrite the program into a windows application format. If you feel you are suitably skilled it would be good to discuss this as well.

Many thanks,
