DSOscope firmware, REV A02:

This firmware in this directory is for the DSOscope version of the PPMScope.

The major difference is the DSOscope uses the newer PIC16F887 device
 instead of the older and soon to be obsolete PIC16F877A.  The area
 of change is mainly the setting up of the PIC16F887 serial port
 communications.  Also, since the DSOscope hardware does not
 support/utilize the PPMScope parallel port/I2C, those interface
 methods have been dropped from the DSOscope firmware.
