The CDC CC617 terminal was a special purpose terminal built for Ticketron ticketing services. The CC617-A variant contains firmware specifically for Ticketron ticket sales while the CC617-B variant contains generic firmware that bootstraps downloaded firmware for a particular application.

The hardware uses a card-cage design with 10 slots. In the CC617-A variant the cards are as follows:

  • 2x +5 V switching power supply regulator cards
  • 2 KB ROM card
  • 2x 4 KB RAM card
  • processor card
  • STIC (special timing and interrupt control) card
  • asynchronous interface card
  • display/keyboard interface card

In the CC617-B variant the cards are as follows:

  • 2x +5 switching power supply regulator cards
  • optional program memory module card
  • processor card
  • STIC card
  • asynchronous interface card
  • optional modem card
  • display/keyboard interface card

The keyboard does not use a QWERTY style layout and has special keys oriented towards ticket sales. A keyswitch on the keyboard has OFF, ON and MGT (management) positions to secure the terminal against unauthorized ticket sales. The cable connecting the keyboard to the terminal uses an 8-bit parallel connection for key codes and a 2-bit parallel connection for the state of the 3-position key switch, as well as power, ground and control signals.
