It was from here:

https://cdn.netbsd.org/pub/NetBSD/NetBSD-10.0/images/NetBSD-10.0-macppc.iso

I also tried NetBSD 9.4, downloaded from here:
https://cdn.netbsd.org/pub/NetBSD/NetBSD-9.4/iso/NetBSD-9.4-macppc.iso

It also failed, but it went a little further:

I may be able to capture all of the text in a serial console or a telnet
