-- v 069 special solenoids only activated with Game On
-- v070 mapping WPC/De corrected
-- v071 changed flipflop multiplexer for sound
-- v072 another change for flipflop multiplexer for sound ('flipflops_fast' clocked now with 50MhZ)
-- v080 selection Data East for each gamenumber >=32 ( game_select(5) = 0)
-- v081 lamp_strobes / lamp_returns changed at PIA1 ( PA - PB ) was wrong in pinmame s11.c
-- v082 bug: only one sound => clock multiplexer for sound back to 2MHz, flipflop_fast back to v2.0
-- v083 bug with lamp control => lamp_row (returns) output need to be negated
-- v084 busy dmd always 0
-- v085 boot message for alphanumeric
-- v086 start bootmessage early to prevent digit 1  all segments brightly lit at boot
-- v087 prevent display garbage and (short) solenoid&lamp activation at CPU start
-- v088 prevent sounds at CPU start, corrected chars bootmessage, latest flipflops.vhd from WillFA7
-- v089 segments now in RAM, added bootmessage for 2xalpha + 2xnumeric ( via gamedef.qip & WillFA11.hex ), flipflop clk_div2 external
-- TODo
-- CPU & Sound switch
-- W7 jumper via options
-- mem prot
-- boot message for SYS9
-- all clocks to PLL ?
-- eliminate LED ghosting ( happens also with org CPU )
