There was another Digeec clock on the forum in the past, but I don't think this type used an LSI IC, I'm pretty sure it was just 74 TTL's, but again an impressive clock:

I think I once saw an advertisement in a vintage UK magazine by the EEC company, but I cannot recall which mag or when, but it was from the 1970's.

I found some similar LSI IC's, not in ceramic packages though, with differences in the pin configurations and complimented BCD outputs.

It was quite a job to copy out the schematic of my clock, if I hadn't I wouldn't have been able to figure out how to get it to run on 50Hz mains.
