Open 7400 Competition / [Entry] Lineclock

I build this clock with an old display-board from an east-german numeric control. It has a one-line display with 32 5x7-dot matrix displays (old VQC10 from the GDR). The clock shows the time as a text.
The circuit on the breadboard is made out of 14 74HCxx chips and two EPROMS.

You can find more documentation and a small video on my homepage: ulegan [dot] net [slash] lineclock
