Sounds like a plan.
The article seems clear enough to me (and I am NO pro).
The SSD becomes/is the bootable drive and will have a TEST/SPARE home folder. The Time Capsule EXTERNAL HDD will replace the INTERNAL unusable drive which came with the computer. That will just lie there until I can figure a way to get it up and running - if at all possible.
My User Home Folder can be moved to the (former) Time Capsule - as per the instructions - and I will always have it connected to the desktop when I do start up. Seems simple enough.
Presumably, I should erase and format the current Time Capsule to now become my main EXHD. Any special advise for doing so? OS Extended Journaled (according to the article) OR APFS? Further, I may get the internal HDD functioning and someday want to revert back to using the Time Capsule again for Time Machine backups.
Thanks, again, for all your help. In the short term, this looks like a good plan. I have 1 TB external HDD I currently use as backup. I also just bought a 2 TB external HDD to use for a second Time Machine backup.
