/*************************************************************************** Juno First : memory map same as tutankham with some address changes Chris Hardy (chrish@kcbbs.gen.nz) Thanks to Rob Jarret for the original Tutankham memory map on which both the Juno First emu and the mame driver is based on. Juno First memory map by Chris Hardy Read/Write memory $0000-$7FFF = Screen RAM (only written to) $8000-$800f = Palette RAM. BBGGGRRR (D7->D0) $8100-$8FFF = Work RAM Write memory $8030 - interrupt control register D0 = interrupts on or off $8031 - unknown $8032 - unknown $8033 - unknown $8034 - flip screen x $8035 - flip screen y $8040 - Sound CPU req/ack data $8050 - Sound CPU command data $8060 - Banked memory page select. $8070/1 - Blitter source data word $8072/3 - Blitter destination word. Write to $8073 triggers a blit Read memory $8010 - Dipswitch 2 $801c - Watchdog $8020 - Start/Credit IO D2 = Credit 1 D3 = Start 1 D4 = Start 2 $8024 - P1 IO D0 = left D1 = right D2 = up D3 = down D4 = fire 2 D5 = fire 1 $8028 - P2 IO - same as P1 IO $802c - Dipswitch 1 $9000->$9FFF Banked Memory - see below $A000->$BFFF "juno\\JFA_B9.BIN", $C000->$DFFF "juno\\JFB_B10.BIN", $E000->$FFFF "juno\\JFC_A10.BIN", Banked memory - Paged into $9000->$9FFF..
