// license:BSD-3-Clause // copyright-holders:Robbbert /************************************************************************** PINBALL Wico's only game : Af-tor Schematic and PinMAME used as references. Code for the interrupts/timers was derived from PinMAME. Af-Tor was the first pinball to use alphanumeric displays. Each display has 12 segments, but are programmed with 8-bit codes. This makes some of the letters look rather odd, but it is still readable. a a _ _ f/_/_/ b g = 2 middle horizontal segments e/_/_/ c h = 2 middle vertical segments d d Press 9 to enter service/selftest. Press 1 to step through the tests. When you reach the audit stages, press 6 to advance and 5 to clear. In the switch test, it will report any closed dip as a failure. You can ignore these. The game has 2 balls, for multiball feature, so the outhole doesn't work because it thinks the 2nd ball is in play somewhere. To activate the end-of-ball, hold down X then hold down num-9. ToDo: - Add outhole/saucer sound ***************************************************************************/ #include "emu.h" #include "machine/genpin.h" #include "cpu/m6809/m6809.h" #include
