Help with downloading Legacy Psychtoolbox Versions

Hi everyone! I need help with downloading old versions of Psychtoolbox. I need it to run a working memory test program, which is only supported by versions 3.0.9 or older :(


I have Matlab R2016b, and psychtoolbox 3.0.13 installed. I tried running the DownloadLegacyPsychtoolbox code but I get the following message:


% THIS SCRIPT IS CURRENTLY NON-FUNCTIONAL. Contact the PTB forum for

% help if you need old copies of PTB, or check on the PTB website for

% instructions.

Does anyone know how I can download legacy PTB versions?

Thank you so much!
