Need ActiveTcl8.3.4.2 For School Project

[dabench]

I need ActiveTcl8.3.4.2 for a school project but I can't seem to find it anywhere. I've tried google but I can only find the lastets 8.5 version but the tool that I am using for school needs 8.3.4.2. Any idea where I might be able to get an older version?
