TRUTH TABLES FOR PAL IN SUPERQBOARD Issue 1 & 2 512K RAM.

In the SuperQBoard the PAL pins 1 - 9 and 11 are inputs,
pins 12 - 19 are outputs. Pin 10 is ground and pin 20
is +Vcc.

Here are the truth tables:

Output pin 12:                        Output pin 13:

   Board select and DTACKL

          Pins 17 and 18 are feedback outputs used as inputs,
     so the output buffers have to be set at high impedance.
          Pin 16 feedback input is probably used to disable pin
     19 output when high, thus simulating an open collector
     output on pin 19.

;   Board select and DTACKL

;          Pins 17 and 18 are feedback outputs used as inputs,
;     so the output buffers have to be set at high impedance.
;          Pin 16 feedback input is probably used to disable pin
;     19 output when high, thus simulating an open collector
;     output on pin 19.

            Adding a Mouse to an Issue 3 SuperQboard
            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    I have now managed to add the extra bits to my Issue 3 super-
Qboard to get the mouse working.
    It needs two 74HC74s in the  spare 14 pin spaces, and a 74HC244
in the 20 pin space. A 9 pin D type plug fits by the 74HC74 at the
power supply end of the board, and a 4K7 ohm pull up resistor has to
be fitted near the pin 1 end of the 4077 IC (it has no connection with
the IC). The ICs fit in the same direction as all the others on the
board, but some boards have extra holes at the ends of the ICs where
decoupling capacitors have been left out, so the IC position should
be checked with its power supply pin positions. A different version
of the ROM is required, and I can provide this for a small fee for
QJUMP's copyright.  The latest  version of the pointer interface
software from QJUMP should be used, and not the ROM resident code in
the superQboard. If this ROM is fitted without the mouse components
present, the QL will 'freeze' on initialisation. The cure is to fit the
74HC74 at the power supply end of the board, or tie the 5 and 9 pin
positions of this IC space to earth.
    If you fit a board mounted plug you will need to rewire the Atari
mouse socket to suit, as Sandy didn't use the same pinout as on the
QIMI, but I can provide a copy of the connections. I rescrambled the
lead to my plug so as to be compatible with my QIMI set up.

         CONVERTING ISSUE 1 SUPER Q BOARD TO 256 K ROM

 1)Cut tracks between pins 27 and 28 of ROM on both sides of
   board. NOTE: Difficult on upper surface because of socket.
   BEWARE! ROM faces in opposite direction to all other chips on
   board, and socket may not be marked!
 2) Cut track on underside of board which goes to pin 14 of 74HC03
    where it runs alongside pins 13 and 12.
 3) Connect pin 28 of ROM (5v) to pin 14 of 74HC03.
 4) Connect pin 27 of ROM to A14 line (pin 11 of TMS4500 is nearest).
 5) Cut A14 line to 74LS266 pin 9 just beside pin 9 on upper side of
    board. Tricky due to tight packing of chips.(Too many elephants
    in a Mini!)
 6) Join pins 8 and 9 of 74LS266.
 7) Fit 27C256 ROM with Sandy code in lower 16K  and TK2 in upper
    16K.
 8) SEND ROYALTY TO QJUMP IF YOU DON'T ALREADY HAVE TK2 FOR THE SAME
    MACHINE.
         
         

         CONVERTING ISSUE 3 SUPER Q BOARD TO 512K ROM

 1) Cut 5v line to pin 1 of ROM on upper surface of board.
 2) Connect pin 1 of ROM to A15 line; B11 on expansion socket.
 3) Cut line from A15 to pin 1 of 4077 quad exclusive nor.
 4) Join pins 1 and 2 of 4077.
 5) Fit 512K ROM, preferably in socket, with your own code in upper
    32K.
