Sartori, J.; And Others – American Journal of Physics, 1995
Describes hardware that enables the use of an IBM PC microcomputer as a frequency meter or a counter by using the parallel printer port. Eliminates the 16-bit time-day counter through the use of an external time base that can be conveniently set depending on the desired frequency range. (JRH)
