1 Introduction

Allied Leisure (ALI) is best known for making machines with "short" playfields; the two "shaker ball" EM machines, and several "cocktail" pinball machines in the late 1970s, which they produced under the names "Allied Leisure Industries" and "Fascination International" with identical hardware (Gameplan was also making cocktail pinball machines in the late 1970s with completely different hardware based on Bally's designs). They also produced several "traditional form factor" solid-state pinball machines in the mid-1970s.

Some history of Allied Leisure can be found here: Part 1, Part 2, Part 3, and Part 4. Some additional background information on Allied Leisure and their arcade games can be found here.

3 Technical Info

3.1 Board Set

3.1.1 Generation 1

The system with multiple circuit boards has been designated as "generation 1". It was used in Rock On, Dyn 'O Mite, T.N.T., Thunderbolt, and Boogie. All the games used the same cabinet and the same playfield layout (not all had the same artwork). Sounds were provided by a set of chimes. The wiring and components for the power section at the bottom of the cabinet varied somewhat between games.

3.1.1.1 Pinball Lamp Drivers (264-1-53)

There are two lamp driver boards. One of these boards is located in the backbox, and another in the cabinet.

3.2 Connectors & Pin Designations

3.2.1 Generation 1

3.2.1.1 50-pin (25x25) Connectors

The 50-pin connectors have two rows of 25 pins. The front-facing side is numbered from 1 to 25.

On the back row, the pins are assigned letters, but with a few missing (G, I, O, Q) and with a few additions (AA, BB, CC).

When looking at the the front of a board connector:

Pin Assignments for the 50-pin connectors

Pin Assignments

Back Row	A	B	C	D	E	F	H	J	K	L	M	N	P	R	S	T	U	V	W	X	Y	Z	AA	BB	CC
Front Row	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	21	22	23	24	25

The edge connectors on the PCBs also correspond to these pin assignments. There are a few markings to indicate the start and end of the edge connector contact designations.

Front of PCB edge connector showing labels "1" and "25".

Back of PCB edge connector showing labels "A", "Z", and "C" (for "CC").

For boards that use only a single 50-pin connector, pin 25 is always ground and pin 23 is always the supplied voltage for the board.

For the Playfield Logic board, which has two 50-pin connectors, only connector P1B (on the right) uses pin 25 as ground, and pin 23 for the supplied power.

3.2.1.2 12-pin Plug/Receptacle Connectors

There are eighteen 12-pin plug & receptacle connectors throughout the machine. Each plug/receptacle has a number directly below each pin on the inside of the plug/receptacle. Good lighting and a magnifying glass may be needed to see them.

Connector numbering

To separate the connectors, two hands are necessary, since they are always very tightly connected. With one hand, pinch the two contacts tightly. Then, pull on the ridges of the plug. Try to avoid yanking on the actual wires themselves, or they might be pulled from their connectors.

The pins used in these connectors are not the standard Molex 0.084" pin and socket connectors used in most games in later years from other manufacturers. They are AMP Commercial Mate-N-Lok connectors. These connectors are not compatible with Molex connectors, so neither a pin nor socket Molex connector can be substituted. Molex connectors will also not fit properly in the plugs or receptacles.

Various part numbers for pin connectors:

• 60620-1 (Pin, 14-20 AWG, tin-plated brass)
• 60620-4 (Pin, 14-20 AWG, tin-plated phosphor bronze)
• 60618-1 (Pin, 18-22 AWG, tin-plated brass)
• 60618-4 (Pin, 18-22 AWG, tin-plated phosphor bronze)

Various part numbers for socket connectors:

• 60619-1 (Socket, 14-20 AWG, tin-plated brass)
• 60619-4 (Socket, 14-20 AWG, tin-plated phosphor bronze)
• 60617-1 (Socket, 18-22 AWG, tin-plated brass)
• 60617-4 (Socket, 18-22 AWG, tin-plated phosphor bronze)

The pins tend to be corroded and cause connectivity issues. If certain features on your game are not functioning properly, the problem is likely caused by a corroded pin and socket. Additionally, a single signal path may travel through upwards of 5 connection points between the source and destination, so any one of those connectors could be causing a problem because of resistance caused by the corrosion, or lack of any contact at all.

Corrodded pins

Corrodded sockets

It is recommended to replace all the Mate-N-Lok connector pins if there are signs of corrosion. However, the connectors are rather pricey compared to their Molex counterparts, so the cost will add up quickly.

One alternate suggestion is to instead replace everything with standard 12-pin Molex housings and 0.084" connectors. However, the original connector housings are color-coded instead of keyed, so the color coding would be lost and it would be very easy to mix up the plugs and receptacles and connect the wrong ones together. Also, it is currently not confirmed if the standard Molex housings will fit through the mounting brackets.

Since there are different gauge wires in use, and some cases where two wires are crimped into a single connector, a small number of 14-20awg connectors will be needed, but the majority of the will be 18-22awg.

To remove the connector pins, a small pair of needle nose pliers will be needed. To remove the socket connectors, a Waldom W-HT-2038 will be needed.

3.2.1.3 6-pin Plug/Receptacle Connector

There is one 6-pin (3x2) connector for the chime assembly. Everything that applies to the #12-pin Plug/Receptacle Connectors also applies to this connector.

3.3 Switches

3.3.1 Generation 1

All the game's switches feed into the Playfield Scoring Logic board. At least one LED will light when a switch makes contact. Some switches only trigger one LED, while others can trigger several.

By default, all the LEDs should be off except for the power LED and the outhole LED. If drop targets are in the down position, LEDs will also be lit for those until the game goes through its playfield reset cycle.

3.3.2 Generation 2

All generation 2/3 solid-state ALI / Fascination games use the exact same MPU board and software; game "rules" are changed simply by rearranging the placement of switches, targets, lamps, pop bumpers, and other elements on the playfield.

4 Problems & Fixes

4.1 Fuse Holders

The fuse holders in all full-size Allied Leisure pinball machines are known for poor tension and clips breaking easily because of the thin, weak metal that was used. This can lead to intermittent and unreliable operation.

In order to ensure proper and reliable operation, go through and replace all the fuse holders. This is a required modification.

• 

  A strip of original fuse holders. Notice that at least one of the fuses is basically falling out of its holder.

• 

  An original fuse holder strip. Notice all the bent and broken clips.

• 

  Fuse holders replaced with Bussmann BK/S-8001-1-R holders in Dyno-mite.

Make sure to label the wires in some way before desoldering so that they don't get mixed up accidently. The easist way to desolder the holders without accidently melting the insulation on neighboring wires is to start with the bottom most fuses of each strip and work your way up.

Drill a hole on each black dot for each mounting screw. This way, the fuse holder will be level with the labels and it will be easy to tell which label corresponds with which fuse holder. A #6 1/2" screw can be used to mount each new holder.

When soldering the wires to the new fuse holders, start from the bottom most fuse, and work your way up. This should help prevent the soldering iron from accidentally grazing and melting the insulation of neighboring wires, like when desoldering the original strip of fuse holders.

5 Parts Substitutions & Replacements

5.3 Cabinet

5.3.1 Playfield Rails

The playfield rails inside the cabinet appear to be nearly identical to the playfield rails found in Gottlieb System 1 games. However, the Allied Leisure rails are painted what what looks like a heat-resistant flat black, rather than left bare.

5.3.2 Legs

Generation 1 Allied Leisure legs are 29.5", painted gray, and have a 5-1/4" rib (instead of a rib going down the whole length of the leg). The leg is pinched slightly around the length of the rib. The original part number was 264-3-42.

A Gottlieb 28.5" dark gray non-ribbed leg might be a close possible substitution (Part LEG-28GR from PBResource).

A Williams System 11 28.5" half-rib leg might also be a close substitution.

7 Documentation

7.1 Incorrect Labels

7.1.1 Incorrect Fuse Labels

On Dyno-mite, the bottom panel has an incorrect fuse value for the 5VDC fuse in the upper left. 5 Amp is printed on the label, however, the schematics call for an 8 Amp fuse. For later games, be sure to check the schematics to verify the correct fuse value.

7.1.2 Incorrect Relay & Timing Circuit Labels

In Dyno-mite, the row of relays on the bottom panel correctly correspond to their labels. However, the "Timing Circuits" that correspond the Relays for targets A through D are mislabeled.

The left-most terminal strip in the timing circuits section should be designated "D", followed by "C", "B", and "A" all the way on the right.

The row of relays. Note that the bracket that normally secures the relays has been removed.

The row of terminal strips in the timing circuits section. Note that the labels are incorrect. The left-most label should instead be "Target D" and descend alphabetically to "Target A" on the right.

To check which terminal strip is associated with each relay:

1. Remove relays for targets A through D from their sockets
2. On one of the the terminal strips in the "Timing Circuits" section, touch one of the multimeter leads on the bottom terminal (closest to the bank of relays).
3. Use the multimeter's other lead to probe pin 14 of each relay socket until the multimeter buzzes. When it buzzes, label the terminal strip appropriately to match the relay's label.
