I recently found an artikel in Elektuur (now Elektor) that resembles part of the Exachron circuit. It was published in Dutch Elektuur 137 January 1975 (on pages 5 to 8). The article explains how the MMVs in the 74123 detect the DCF_in signal being '1'or a '0'. And how that information is shifted into the 74164 register.

You can find that magazine and lots of other electronics magazines movies and books on:

In reply to Humberto.

Despite the dislikes I believe it indeed was a good informative article. So I am happy about that Humberto. I do not know however if I qualify to be called a Professor, but I humbly absorb your nice comment.

Hi Albert, do not get sad about the dislikes, maybe some people did not understand well your article. In my own opinion you have done a correct work, very scientific and of course you have dedicated some time to study and redact your nice article. So congratulations Professor.

Thanks Robert. It also must have been more work than usual for Jestine too. But all for the greater good called Electronics.

In reply to Albert van Bemmelen.

About the free TI Tina version 9.3.150.4: I just re-checked the program.
The Oscilloscope and other Tools work splendidly, it even has the VHDL (mixed mode?) function and is almost a standard Tina version, but it doesn't animate the circuit in any simulation. And there is no button for it either. Neither is the PCB designer integrated. Nevertheless it does give allmost all else in a Spice way on screen (like my version 10 and 11). Even the temperature calculation and so on, which my 600 euro Tina version does too.
