ATSXL is an overlay to FOCAL-RT (DECUS 12-80) which allows a 'frame' of text to be presented on the display and the subjects response, response time and keydown time to be recorded. Up to 511 frames of up to 510 characters each may be randomly presented allowing adaptive techniques to be employed. Once the stored frame has been found display presentation is immediate. Up to 12 bits of response information can be recorded and timing is to an accuracy of 10 milliseconds. Responses are input on the external sense lines.

Minimum Hardware: 8K PDP-12 with dual LINCtapes, VR14 display, KW12A real-time clock and sense lines
