Abstract
Procedures are described for the IBM PC/AT and compatibles that measure an event’s duration with millisecond accuracy and that synchronize stimulus presentation with the vertical-retrace signal. The software is written in Turbo Pascal (Versions 2.0, 3.0, and 4.0; Borland International, Inc., 1984, 1985, 1987). Difficulties reflecting differences among video controller cards are also presented.
