The Ceres workstation had a special key which interrupted the system and
returned control to Oberon.Loop. It was detected in the keyboard
interrupt handler, Input.KBINT, and causes a Trap(24). See Project Oberon
Ch. 9.2, pp.260-261 (PDF p.208).

Yes, it's 1024 x 768 x 1bit, using 96KB of the external 1MB SRAM.
