+ Poly-Play
+ (c) 1985 by VEB Polytechnik Karl-Marx-Stadt
+
+ driver by Martin Buchholz (buchholz@mail.uni-greifswald.de)
+
+ Very special thanks to the following people, each one of them spent
+ some of their spare time to make this driver working:
+ - Juergen Oppermann and Volker Hann for electronical assistance,
+ repair work and ROM dumping.
+ - Jan-Ole Christian from the Videogamemuseum in Berlin, which houses
+ one of the last existing Poly-Play arcade automatons. He also
+ provided me with schematics and service manuals.
+
+
+memory map:
+
+0000 - 03ff OS ROM
+0400 - 07ff Game ROM (used for Abfahrtslauf)
+0800 - 0cff Menu Screen ROM
+
+0d00 - 0fff work RAM
+
+1000 - 4fff GAME ROM (pcb 2 - Abfahrtslauf (1000 - 1bff)
+ Hirschjagd (1c00 - 27ff)
+ Hase und Wolf (2800 - 3fff)
+ Schmetterlingsfang (4000 - 4fff)
+5000 - 8fff GAME ROM (pcb 1 - Schiessbude (5000 - 5fff)
+ Autorennen (6000 - 73ff)
+ opto-akust. Merkspiel (7400 - 7fff)
+ Wasserrohrbruch (8000 - 8fff)
+
+e800 - ebff character ROM (chr 00..7f) 1 bit per pixel
+ec00 - f7ff character RAM (chr 80..ff) 3 bit per pixel
+f800 - ffff video RAM
+
+I/O ports:
+
+read:
+
+83 IN1
+ used as hardware random number generator
+
+84 IN0
+ bit 0 = fire button
+ bit 1 = right
+ bit 2 = left
+ bit 3 = up
+ bit 4 = down
+ bit 5 = unused
+ bit 6 = Summe Spiele
+ bit 7 = coinage (+IRQ to make the game acknowledge it)
+
+85 bit 0-4 = light organ (unemulated :)) )
+ bit 5-7 = sound parameter (unemulated, it's very difficult to
+ figure out how those work)
+
+86 ???
+
+87 PIO Control register
+
+write:
+80 Sound Channel 1
+81 Sound Channel 2
+82 generates 40 Hz timer for timeout in game title screens
+83 generates main 75 Hz timer interrupt
+
+The Poly-Play has a simple bookmarking system which can be activated
+setting Bit 6 of PORTA (Summe Spiele) to low. It reads a double word
+from 0c00 and displays it on the screen.
+I currently haven't figured out how the I/O port handling for the book-
+mark system works.
+
+Uniquely the Poly-Play has a light organ which totally confuses you whilst
+playing the automaton. Bits 1-5 of PORTB control the organ but it's not
+emulated now. ;) (An external artwork file could be created that simulates
+this.)
