These are the only clones I've seen, but if any more exist I doubt they will entirely use 74 series for the ZMC2/CT0 logic, at ~16 chips (some uncommon) it would be too expensive and difficult to initially design.
It looks like the "Goldstar" version has the logic in the 4x 22V10, 1x 16V8, 4x '153 and maybe the neighboring '32. It's not very efficient because they aren't using the 22V10 to its potential, they could have eliminated the '153 and also eliminated the 16V8 with minimal 74 series.
The "Gobit" must have it in the "ECW" chip which appears to be a mask clone of the CT0. --Kyuusaku 19:10, 26 June 2012 (CEST)
