Thanks
I am using a ttl to USB that is set to 3.3 v volts. I proved it was OK before use with a 'scope.
I can send "hello" from Mac to Kobo as I said above.
I am never offered a log in option
I see
Hit any key to stop autoboot: 0
in the first boot sequence.
I hit keys to no effect.
Must you hit a key to see a log in request?
=======================================
At Debian power down I see ---
xinit: connection to X server lost
waiting for X server to shut down Server terminated successfully (0). Closing log file.
E-ink display autoupdate disabled.

There are differences between boot sector and its backup.
