So... I downloaded the "powerpc" netinst iso from ports/snapshots/2021-10-20/ and burned it to a CD-R (the CD-RW's I had on the shelf were so old they couldn't be recognized in the burner)   It booted fine and I chose to do the default non-graphical install in non-expert mode.  I accepted all the default options up to partitioning disks, where I chose "guided -- use entire disk" with "Separate /home partition"  this resulted in a partition scheme with a hfs partition mounted on /boot/EFI but no /boot partition per se.  I assume this means that /boot should be included in the root partition and that the new Grub would be able to find it, and the kernel/initramfs contained therein.  So I accepted that scheme and allowed it to proceed.

When it got to "Install the GRUB boot loader" it failed with this message:
    Unable to install Grub in /dev/sda3
    Executing "grub-install /dev/sda3" failed
    This is a fatal error

I called it to continue without installing grub and when it rebooted, it gave me the grub menu, but was unable to load the kernel and initramfs.

Did I do something wrong?

Next step is to boot from the CD into "rescue" mode so I can get the installation log files and post them here.

Thanks for any help you can give!
