The 6498 Memotron is a reliable, all-electrostatic five-inch bistable direct display storage tube, designed to capture and retain complex electrical traces and transients which could otherwise only be analyzed and studied through the comparatively low brightness CRT's and elaborate photographic procedures, or by total reliance on the necessarily superior visual acumen of the observer. For comparison of successive wave forms, transients may be superimposed one upon the other, or vertically "stacked". Displays occur at uniform brightness regardless of writing speed. The brightness of the stored presentation is such that it can be viewed under conditions of high ambient light, such as those encountered in well-lighted laboratories, and it remains stored until it is intentionally erased.
