Timing accuracy of mouse response registration on the IBM microcomputer family

Data and theoretical estimates reported by Segalowitz and Graves (1990) and Crosbie (1990) regarding delays of serial Microsoft mouse response registration are corrected and extended. Empirically measured mouse responses clearly confirm a theoretical minimum delay time of 22.5 msec for Microsoft-compatible serial mouse devices. Timing accuracy of key actions for the serial, bus, and PS/2 mouse devices are presented.
