SongCode Hardware Setup

The PTT Kooser Control System was the special setup used for controlling and programming animatronics at the second ever Pizza Time Theatre location, San Jose, CA (1371 Kooser Rd), before its switch to Cyberamics in 1980.

PDP-11
The PDP-11 is the main computer for the system. It is unclear which model of the PDP-11 was used, as the usual towering mass of a standard unit is unseen in any photos. It is stated the hardware has 32Kb of memory, alongside a dual floppy disk drive and other various peripheral electronics.

ADM-3a
The ADM-3a was the visual display computer for the entire system. It was also presumably running the SongCode predecessor, as it is seen displaying SongCode-like signal instructions in the Kooser news video.

A large black device with a PTT label is seen on the back of the ADM-3a, in a spot connected exactly to the unit's rear RS-232 expansion port. It is unclear if the unit is a generic one with a PTT label, or a special PTT device used for running the software.

CEC Tester
The CEC Tester is a small blue device used for controlling animatronics.

It is unclear if the unit's name was actually CEC Tester, as its only image with a name comes from an early version of showbizpizza.com in the 2000's, in which it is stated as "CEC Tester- This is another type of tester used at CEC. I can't say precisely what it does, but it has manual controls on it.". Despite the website having a source able to provide its exclusive image, it is dubious at best if the description of its function is accurate to its true function.

Kooser Footage
In 2017 brand new footage of the Kooser Road location would surface, which would provide a glimpse of the device being used at its store. An employee is interviewed regarding the control systems behind the animatronics, in which he states, while referring to the device itself, "What this actually is amounts to is electronic puppeteering, only instead of having strings, you have buttons, switches, and joysticks.", confirming the device is used to control the animatronics.

Between splices of other character footage, the employee can be seen demonstrating to the interviewer him using the unit, alongside pointing outside to either the main showroom or the Dolli Dimples showroom to presumably show a character he is controlling. His main movements are of using the joysticks, suggesting they are the main practical use for controlling the characters.

Analysis
From the layout of the device, and the comment of the Kooser employee, it can be determined that the 8 labeled directions of the 2 joysticks, 8 switches, and 8 buttons all are various ways of controlling a single character, allowing movements to be stuck on, manually pushed on, or dynamically controlled with a joystick. The system of eight movements per character is similar to later developed Character Card system of the Cyberamic Control System, in which each animatronic has given a special card denoting 8 movement slots for the character, and 8 for lights and effects.

The more sophisticated controls of the device leads it to being used for animatronic programming rather than diagnostic testing, and its other interface controls likely played a role in switching between characters, and communicating with its attached computer for saving programming data.

Setup
The entire setup in the SongCode image is comprised of a variety of hardware. Going from left to right:

Top Row

 * Unknown Device (Blue & Gray)
 * Yamaha RM804
 * VT100 (Unknown Submodel)**Likely just used as a display terminal connected to the main PDP 11/23 unit.
 * Unknown Monitor
 * Unknown Control Device (Below Monitor)
 * TASCAM OB-44 Tape Deck
 * Used for playing Rock-afire Explosion Showtapes, same model as used in the Grey Box.

Bottom Row

 * Red Panel**Wires are hanging from under it, could be housing the Grey Box system for controlling the Rock-afire Explosion stage.
 * Cyberamic Control System
 * Used for controlling the Cyberamic stage.
 * A small section above the character cards has been used for some patch panels.
 * Unknown Device (Gray, Potentially the back of a small tape deck)
 * TEAC A-2340 Tape Deck
 * Used for playing Cyberamic Showtapes. Notably not the version used in the Cyberamic Control System, but rather the PTT Kooser Control System.

Other Hardware
The main hardware out of frame is the PDP 11/23, which is the main computer running the SongCode software. It could've potentially been stored in a seperate room due to the device being noisy when running.
