Rev 1.2:   At composite 0ohm jumpers. R62 NTSC Location was connected to ground and should ACTUALLT be connected to
      RGB port (23pin) pin 15.  no idea why this fuckup was.  Corrected here.. so earlier versions of board
      and if you want composite/svideo in NTSC middle pad of R62 shold be connected to RGB Pin 15 instead of a
      jumper. PAL Is not affected

      IF using a VideoDAC that requires a Zenerdiode, I have now connected the R215 Correctly (was wrong on older
      versions not connected to +5V.   so you must put a 1K resistor here if that DAC is used. on older rev.
      you need to connect the 1K resistor on RIGHT pad of C215 and to +5V (like top pin of D233A)

      Added Kickstartswitch functionality,. if you are using 27C800 proms. you can program one bank with one
      kickstart and the other bank with another.  if R6A (bottom side of board) is set to ENA. the jumper can
      select the active bank. High/low  with moving a jumper or a switch. (or a pic controller of your choise)
      if R6A is set to DIS, the A18 signal is handled as on any Amiga.
      to make some kind of PIC for this controlled by joystick fire or mouse left. FIR0 and FIR1 have been equipped
      with a TH hole for soldering a wire there.

      On older rev. you needed to do a slight solderblob at the pads close to U10 (between it and the FPU location)
      this is now a trace. Trace is visible so if you need another "strange" budgie configuration, just cut that
      trace and do your stuff.
