requires original 80-column firmware (for emulation, "Apple IIe" mode in AppleWin, "Apple IIe" mode in MAME) for double-hires mode.
the enhanced 80-column firmware has an undesirable behaviour that resets the X co-ordinate during the call to print in 80-column mode.
this results in only the first chararacter per call being placed correctly, the rest being somewhere on the left side on the screen.
