Looking for data on MA1032-929

Hi,

Long ago I built a digital clock using a National module (not chip) called MA1032-929, from instructions on a magazine (could be Elektor), which I can not locate.

It no longer works, possibly a misplaced cable, I hope. But I don't have data on the module, and I can not locate it on Internet - Google finds places that claim to sell it, or magazines with adds for it.

Somebody knows where to find the data sheet?

You can see a photo here:

Thanks :-)
