Last updated: March 18, 2012 (DOS software update)
The original design seems to be from the July 1998 issue of the
American magazine ELECTRONICS NOW.
A description can be found on
Ian Purdies website.
This design uses only the oscillator part of the original design.

The switches in the original design have been replaced by relays driven from
the LPT port. The way the oscillator frequency is measured can be found in
the description of the
80 MHz frequency counter
Archive containing the Xcircuit files (encapsulated postscript), the C-sources and a DOS executable.
