I'll get a GitHub repository started (using 1.5.5e-3 as the change-basis), then with the community's help on identifying the changes we can get this template up-to-date.
OK, I've got the responsive_classic files (and support functions) pulled out from the Zen Cart 1.5.5e distribution and available on GitHub here: https://github.com/lat9/zen_responsive_classic

I haven't been keeping a change-list for the plugin's files thus far, so any changes needed will need to be (re-)identified, either here in the support thread or via a GitHub issue on the template's repository.
