MacPorts for High Sierra?

[Dave Horsfall]

I had to upgrade this old MacBook Pro (mid 2010) from Sierra to High 
Sierra to run some software that I needed, and now I find that MacPorts 
wants Big Sur which this thing won't run (and I can't afford a new one).

So, is there an old version of MacPorts somewhere that runs on HS?
Thanks.
