  RA+A Spectrum I+

  The Spectrum I+ was a modified Vectrex. It had a 32K ROM cart
  and 2K additional battery backed RAM (0x8000 - 0x87ff). PB6
  was used to signal inserted coins to the VIA. The unit was
  controlled by 8 buttons (2x4 buttons of controller 1 and 2).
  Each button had a LED which were mapped to 0xa000.
  The srvice mode can be accessed by pressing button
  8 during startup. As soon as all LEDs light up,
  press 2 and 3 without releasing 8. Then release 8 and
  after that 2 and 3. You can leave the screen where you enter
  ads by pressing 8 several times.

  Character matrix is:

  btn| 1  2  3  4  5  6  7  8
  ---+------------------------
  1  | 0  1  2  3  4  5  6  7
  2  | 8  9  A  B  C  D  E  F
  3  | G  H  I  J  K  L  M  N
  4  | O  P  Q  R  S  T  U  V

  6  | $  %  &  '  (  )  *  +
  7  | ,  -  _  /  :  ;  ?  =
  8  |bs ret up dn l  r hom esc

  The first page of ads is shown with the "result" of the
  test. Remaining pages are shown in attract mode. If no extra
  ram is present, the word COLOR is scrolled in big vector!
  letters in attract mode.
