If the LE and DS pins (5 and 6 on IC 74c926) are in logical 1 (for ex. with an ls04),
the circuit is working (it runs, displays something, not only 0000).
I don't know why but it's not perfect yet... (maybe wrong modell...)

P.S.
I think the frequency of the internal multiplexing and the main clock are in conflict.
Change the value of the C2 to 100nF and see...

Hi!

As I wrote (here: http://www.sonsivri.com/forum/index.php?topic=681.0),

"Please to consider the multiplexed displaying works in the "human eyes" only, beacuse it displays one digit at a time. Press "pause" at times in the Proteus simulation..."

The Proteus simulation speed isn't great enough for the real-time multiplex displaying

I uploaded the working but a bit simplified DSN file:

Hope this helps.
