Yes, there is. But there sometimes were problems:
- it was once on ftp.freebsd.org, then it was deleted by accident, then
it was there again. The miniroot's (the small thing) age and the story of
the 32M - image made me anxious that similar could happen in future.
Maybe I missed an easy way to boot the first MIPS DEC or something about
that in the web and documentation. I don't see why the diskimage.tar.gz
would be useful for something like that in any way. OpenBSD installation
seemed a lot easier, and I installed NetBSD-pmax using the OpenBSD
32M-diskimage.
Sorry for sending a unspecific complaint to the list.

It was just that we (some friends and I) did not manage to get a 3100
boot from network. We got boot requests, reverse ARP requests and tftp
requests from the DEC, but after that, nothing happened. Then we didn't
want to work on this any longer and got the OpenBSD bootimage, because
trying to get a disk with the NetBSD miniroot labeled from the helper
machine failed.
Maybe the reason is that the helper machine is a vax-ultrix 3.1 :-\
(no, we can't simply install netbsd on it. It is needed for the users.)

I'm looking forward to a quick install of NetBSD 1.3 with a 32M-image.
