Looks like binary downloads are on another page and not necessarily made by tcl-lang

https://www.tcl-lang.com/software/tcltk/bindist.html

From that page:

- Android 8.6.10 https://androwish.org/download/index.html

- Activestate seems to require account creation: https://www.activestate.com/pricing/

- Windows, nightly build of 9.0.2 from 15 February: https://gitlab.com/teclabat/tcltk/-/packages/34837768

- Windows 8.6.7 https://www.irontcl.com/index.html

This looks like the link I was looking for: Windows 9.0.1: https://www.tcl3d.org/bawt/download.html#tclpure which links to: https://www.tcl3d.org/bawt/download/Tcl-BI/SetupTcl-BI-9.0.1...
