Yes, I now have two I2C busses. After I cut the solder pad cut-tracks, I soldered a header to the prototyping area, connected up the pads going to the Pi (via the level translators) and hooked up a 20x4 LCD display with I2Cpiggyback board. Running a python demo program produced a message on the display - all good!!!
