Technology
The game is housed in a custom cabinet that includes two sets (one set per player) of three control buttons (up, down, and fire). The game PCB is composed of discrete technology with game sprites stored in ROM. There is an undocumented option available that switches the planes into UFOs. Pin 14 of the 003127 IC — a PROM located at grid location K1 — is tied to ground, but also has a pullup resistor. Cutting the ground trace causes address bit A4 to be pulled high, selecting the UFO data. A jumper can be installed to easily switch back and forth between planes and UFOs.
The vertically set monitor is a black and white Motorola XM501.

Famous quotes containing the word technology:
“If we had a reliable way to label our toys good and bad, it would be easy to regulate technology wisely. But we can rarely see far enough ahead to know which road leads to damnation. Whoever concerns himself with big technology, either to push it forward or to stop it, is gambling in human lives.”
—Freeman Dyson (b. 1923)
