You can access the v1A files via the following link RAMPS-FD Revision 1A
I made some modifications to Repetier firmware to support the inverted outputs on v1A, but I never got repetier working reliably. There was an issue with random shifts of the print head which I haven't figured out. My updated Repetier is here [github.com]. Apart from the inverted outputs the only other changes I made were to the configuration.h file.
I have been using the v1A hardware without modification, but being careful not to leave it with power on.
I recently received a Getech board, it has fuses which is good. I just checked and it has IRF3205, I hadn't noticed before. The IRF3205 is probably ok with the 12V drive circuit, it doesn't look very good for logic voltage levels.
