I'm looking for incredibly outdated versions of PTB - I think any of the PTB-2 versions would suffice, but I'm not 100% on this. In any case, these files appear to no longer be hosted - any link that purports to be a download for these versions leads to a 404.
This is very much one of those legacy equipment running legacy software kinds of situations - my attempts to install 3.0.10 (the oldest version I can actually download from anywhere) are returning messages telling me that my operating system is not supported by SetupPsychtoolbox.
Any help is appreciated.
