MOP boot files

[David Brownlee]

I've been helping dreamlayers with his cleanup of the NetBSD/Linux
mopd, ( https://github.com/dreamlayers/netbsd-mopd ) and we were
looking at how it handled different a.out MOP files, specifically
where the files may be little endian

For non MID zero files its easy enough, but little endian MID 0 files
are potentially more complicated.
https://github.com/abs0/netbsd-mopd/commit/6ab8555817f3dff23c506464d302d1a40bca6214#r43682334

It can netboot Ultrix and the vast panoply of NetBSD MOP boot files in
the various a.out and ELF incarnations http://mop.absd.org/netbsd/
(those that are not broken that is :/ )

I was wondering if anyone had links to hand for any other good sources
of MOP files?

Thanks

David
