Unofficial Cyberamic Control Center Archive

This archive contains unofficial information about the Animatronics Control Computer designed the original Chuck E Cheese's Pizza Time Theatre. The focus of this archive is to document the historical development and capabilities of this machine.

It was reused in several incarnations over it's lifetime:

Reel to Reel Configuration:

• Based on a 6502 processor and a TEAC Tape Deck, this computer controller the shows such as Dolli Dimples, The Beagles, The King, and the Balcony Stage.

SVHS Configuration #1:

• This same hardware was adapted to play media from SVHS Media.

SVHS Configuration #2:

• Upgraded with a M68HC11 processor, and an external media switcher, this continued to be used to play SVHS media.

DVD Configuration:

• Adapted to DVD Media

If you have any more information or experience with this machine, and would like to help document it's history and behavior, please reach out!

Questions:

We're working on collecting as much information on how the original Pizza Time Theater system worked and have generated some questions:

• Did the original R2R system use 4-track audio at any stores?

Backplane:

• Was the original card cage a different size to accomodate the 0004 rev.a card?
• Why is the lights 50-pin connector recessed on the card compared to the character card?

Are there more board revisions beyond what we have? looking for:

• Audio board 0003 rev.a, rev.b, and beyond rev.c
• Audio board 0033 rev.b and beyond
• Character board 0004 rev.c and beyond
• Character board 0034 rev.b, rev.f and beyond
• Light board 0021 rev.b to rev.e
• Transport board 0020 rev.a
• Did the original transport card take a external uart clock? per the schematic
• Transport board 0020 rev.c
• CPU board 0001 rev.d and beyond
• Random movements board?
• Board 0002?

Where are any other rom variants beyond what's in this archive?

• (We strongly believe the original balcony stage rom is not represented here)
• How do the other ROMs handle the buttons on the front panel?

Any more un-scanned documentation?

• Are there any more schematics?
• Any documentation on how to hook up all the shows?

More show tapes on original media?

• More shows decoded?
• What are the formats for the decoding?
• Is there any metadata they missed like potentially more tracks?

Who else to talk to on this subject?

Extra parts we don't have?
