otx is a tool used to disassemble Mach-O binaries on OS X 10.0-10.4. It is an enhancement on top of otool to add additional symbol information to its disassembled output.
The main site and SVN repository (http://otx.osxninja.com/) appears to be long dead. Is there any new maintainer (official or unofficial) or someone hosting the code to disassembly Mach-O binaries on legacy macOS systems?
I posted a similar question on Reverse Enginerring Stack Exchange (Is there an up to date fork of otx?), but it did not generate any activity. To keep this question in-scope, I will only focus on the older versions of OS X, but I am also interested in a version of otx that works on any OS X version.
