Thanks for all the comments!

Regarding the PSUs: I had some blurry photos from during the carry-up that show that the PSUs were in this configuration. Of course they may have been swapped before I got them, I'll sure check the PSU labels before any power-up attempts. I think at least one of the PSUs said Cherokee on the stickers (which looked pretty much identical between the two units).

The DIVO board sounds neat.

I'll have another look on the Octanes (they are not at my home currently) and try figure out more.
