Information for the
1000 Series Dart Game
The following pages are being made available to those that need technical information on
our older dart games. We realize that it is not in any way complete, and that some of the
information is hand drawn, but we are furnishing what we have in case it will help someone.
There are no parts available for these older games, nor is anyone at Arachnid familiar with
them. We hope that what we can provide will be of some assistance.

SECTION 2
MACHINE OPERATION
, . .
2.1 THE 'Game of Darts: the 301 game rules
.
‘The players start with a score of 301 and each dart's score'
subtracted from it. The players total therefore decreases and
approaches zero as the game progresses. Player takes turn at
throwing three darts. As each dart
scores, its score is subtracted
from that players total and his new total is
displayed
changebutton is pressed
'After a player has thrown all his three darts the player
, he takes his darts out of the board
and the next person takes his turn.
WIN a game, a playerhas to make a
score which reduces
his score to zero exactly. This may happen 'with the first,
second or third dart of his turn. When a player's score equals
exactly ZERO the machine will:
-
(i)
set up a GAME OVER situation
(ii) indicate that payer has WON
(iii)prevent any inputs from having any effect,
except for coin insertion
(iv) drive a gong
As a players score approaches ZERO, he
may hit a number which
is greater than he requires to WIN. As with a WIN, this could
happen on the first, second or third dart. This situation is called
a
BUST. When a BUST situation occurs then the.machine will: -
(i)
recall the player's score immediately prior to his present
turn and display it. If a player BUSTS on his first dart, he
.
will not notice any change in his score but busting on darts
2 or 3 he will notice that his score reverts to what it was
before throwing the first dart.
(ii) turn on the "BUST" lamp
(iii)drive a buzzer
(iv) prevent any further score from being recorded.
After achieving a bust the player then abandons his turn, presses
the plaver change button and recovers his darts from the board. With
this action
the next player is brought into the game and the BUST
lamp is cleared. (The score for the player who bust is not changed
by pressing the player change button).

The Displays on the English Mark Darts machlne.
( i)
four sets of three decades (hundreds, tens and units)
of LED (light emitting diode) displays--are for each
player.
These show the players score during the course
of the game. Further they indicate how many players are
in a game as the players score is only displayed if
sufficient coins have been inserted.
(ii)
four
'Player Turn' indicator lamps
(
iii)
four 'WIN' indicator lamps,are associated wfth each

2.3 Other Outputs.
The Bust buzzer and the Win gong are both inside the
upper cabinets and the Board Illiumination lamp has a socket on
the right hand side of the upper cabinet.
The Board Illumination lamp is
turned .on after the
first coin is inserted and goes off about 1 second after the game
has been won.
2.4 The Action of the Coin Mechanism
The first coin inserted after either
(
a)
the machine has been switched on, or
b)
the machine is in a WIN (or GAMEOVER) condition, or
cl
the
'player change' button has been pressed,
will
set up the game for 1 player
Subsequent coins will add to the number of players in the game.

SIGNAL DESCRIPTION LISTS
NUMBERING SYSTEM
All signals going into or coming out of the individual
circuit cards have been designated a unique number.
-The simple code has either a P or an L initially and this
signifies whether the ACTIVE portion of that signal is
long term or transitory.
-The second digit is either a 0 or a 1. Again this designates
the ACTIVE part of the pulse or level to be a logic 0 or
a logic 1.
-From then on they are listed numerically.
CARDS AND PIN NUMBERS
Underneath each card type is a bracket number. That is the
pin number associated with that signal. On occasions where
there are 4 similar signals, going to, or coming from,
the 4 PSD cards the signals are subscripted
a,b,c,d.
In
these cases 4 pin numbers appear in the listing an these
are in the sequence of
a,b,c,d.

SECTION 3 CABINET AND FIXTURES
3.1 Cabinet
The machine. comprises an upper and lower cabinet. The lower
cabinet houses solely the coin
mechanism and is accessible only
from the front in the coin door. All the remainder of the game
is contained within the upper cabinet. Access to this is
through the door on the rear.
The wiring diagram, drawing SAD01 6, provides a schematic
representation of the wiring within the cabinet and also gives the
colours of the individual wires in the cableform.
The Component Parts List details all the major items in the
cabinets and from these two data sheets, the essential features
of this machine can be recognized.
All the low voltages used in this machine are derived from the
one transformer mounted in the base of the upper cabinet.
It has
been conservatively rated and is unlikely to fail. However if it is
necessary to check it, an A.C. voltmeter ought to give a 10 volt
reading between red/yellow lead and both of the yellow leads and
a 12 volt reading between the green/yellow lead and both of the
green leads.
3. Buzzer and Gong
The two devices are activated during the course of a game,
the buzzer to tell the player that he has gone beyond zero and the
gong to tell him that he has achieved zero.
The buzzer is driven from a
115V A.C. signal and may need occasional
adjustment of the screw holding its mounting bracket to the
cabinet (the lower of the two screws) to obtain the loudest buzz.
The gong is driven from a 24V A.C. signal and has no'means of
adjustment.
3.3
Coin Mechanism
The need for regualr cleaning of this item is the same as for
coin mechanisms generally in vending machines. (Notes on this
are to be found in section 7). The optional resistor
Rl of 100 ohm
shown on the cabinet wiring schedule (Drwing number SAD0126) prevents
the [machine from giving free games when the coin door is hit violently,
causing the microswitch to make a momentorary contact.

.4.4
Diode Matrix
Each segment's switch contacts are connected to a printed
circuit card which is assembled to encircle the outer ring of
switches. (The card is
21/2" wide by 48" long when laid flat
prior to assembly).
The singles, doubles and triples are connected by red, blue
and white wires respectively. A common line joins all other contacts
of the 81 switches.
This printed circuit card contains an encoding diode matrix
which encodes each score into a plain binary word of 1,2,4,8,16
and 32. Drawing number SAD0121 illustrates this technique.
A cableform connects this matrix to
PL9 of the Motherboard.

SECTION 5 ELECTRONICS PACKAGE
5.1 Component Parts
The electronics package comprises 8 plug in printed circuit
component cards (daughter cards) approximately 8" x 5". Which
fit into a printed circuit motherboard. The motherboard is
approximately 21" x 8" and houses the 4 sets of the 7 segment
displays, the lamps which illuminate the various captions and
edge connector to connect to the cabinet cable.forms.
Of the 8 plug in cards, 4 are identical. Giving 5 different
card types. Each type is described in the sections following
the motherboard description.
Each of the card types has a keying slot in the connector
edge to prevent incorrect insertion of either the wrong card type
or that plug or the right card type but inverted.
5.2 The Motherboard
The Motherboard is a printed circuit card containing all the
interconnecting links of the 8 daughter boards and the links to the
LED displays. It also serves as a fixing point for the reservoir
capacitor for the major +5 volt logic supply line.
Two edge connectors, PL9 and PLlO, connect it to the cabinet
cableform and 8 $"
screws fix the motherboard to the front of the
upper cabinet.
The description of the operation of the electronics package is
contained in mainly the individual sections for each card type
but here signals appear on the motherboard, then these signals
are assigned a code and are described fully in the subsequent signal
description lists. This has been made part of the section on the
motherboard for convienience.

5.3 The Score-to-Pulse Conversion (SPC) Card
(PLl) on Motherboard)
The 6 encoded inputs PO-01 through PO-06 (weighted 1,2,4,8,16,32
respectively) from the dartboard and its diode matrix are the prime
inputs to this card. Because of the non uniform nature of the
dartboard signal, each of these six are conditioned into uniform
pulses, around 50 milliseconds long, by monostables
(IC's 3,2,6,1,
4, and 5 resply),
The outputs of these monostables are- clocked into registers
IC7 and IC9 by means of a clock pulse from ICll.
This clock pulse
can be inhibited by LO-15 and LO-20 and these are used to prevent
a score registering in the case of a win or a bust.
When a score is made,
IC20, a 1OKHz oscilletor is gated to start.
Pulses from it fill up a counter, (IC16 and
IC14) and when the number
in it is the same as the score, then a 6 bit comparator (IC15 and IC19)
stops the oscilletor.
Pulses are output from this card on pins 15 and 17 as Pl-08
and Pl-09. Only Pl-09 is used and is routed to the GPM card.

(Complete Assembly)

5.4 The Game and Player Management (GPM) card
(PL2) on the Motherboard)
The major function of this card are:
(i)
to count the number of coins and hence the number of
players in the game.
(ii)
to sequence the players' turn when the player change
button is pressed .
(iii) to distribute the score pulse train (from the SPC card
(PO-09) to the appropriate PSD card).
(iv)
to reset the game to a 'GAMEOVER' condition with power on.
The pulse from the coin mechanism, PO-lo, triggers a monostable
IC12 which clocks a 4 bit shift register IC18. With suitable
buffering, the 4 outputs of this register leave the card as LO-02
(a) through (d) and are routed to each PSD card. (There they allow
currents to pass through the players score LED's). Pin 6 of IC18
.is a 'mode control' input and will allow IC18 to shift right or to
have a parallel input. The parallel input is 1000 and occurs when
the first coin is inserted (see sect 2.4). A register,
IC19, controls
this, it being set by a 'player change' signal (PO-11) or by the
machine being powered up. It is cleared by the coin mechanism pulse.
Operation of the 'player change' button will trigger a 5 second
monostable, IC24 which, if LO-15 is a logic 1, will trigger mono-
stable IC22. During this 5 second delay, signal LO-22 inhibits
scoring as the SPC card and signal Pl-25 operates, via a relay driver
circuit on the LDPS card, RLl on the Motherboard. (This controls
the caption'lamps, changing THROW DARTS to REMOVE DARTS as the
illuminated caption for the 5 seconds).
IC22 output is or-ed with the coin mechanism pulse in IC6
gate 1 and buffered in IC3 gate 1 to give PO-17. This pulse feeds
the WBD card to reset the BUST register. This output from
IC6
gate 1 also is used as the clock for a second 4 bit shift register,
ICll.
The combination of gates using IC's 16 and 20 and parts
of IC'S 15, 4 and 17 control the 'mode control' input of
ICll.
Essentially they allow a parallel entry of 1000 for the first
player and then a shift right every time the 'player change' is
pushed. If 2 players are playing,
ICll cycles through 1000, 0100,
1000,0100 etc. If 3 players are playing it cycles 1000, 0100, 0010,
1000, 0100, 0010 etc. and for 4 players it cycles 1000, 0100, 0010,
