Vanilla 5-clock is way outdated even for MC 1.2.5. That's was like pre-redstone repeater era. Which is probably before MC 1.0 lol.

Make a regular clock, the one with one torch and as many repeaters as you want, linked in a loop. Alternatively, you can make a delay line based loop, using only repeaters linked in a loop and a 1 tick redstone pulse to start it. Unless they went along and disabled entire vanilla redstone too, it works fine. And sequencers can work also if they didn't connect the dots and limit that too.
