The Sun3 port has support for making boot tapes, and I believe
it works exactly the same way for the sparc port, so you should
be able to use src/sys/arch/sun3/stand/tapeboot as a start.
That is used, along with src/distrib/sun3/{ramdisk,miniroot}
to make a boot tape with the following "MakeBootTape" script:
(which I have fogotten to check in anywhere...)

#!/bin/sh

# Here is a generic script that makes a Sun3 boot tape using
# the files in this directory.

T=${1:-/dev/nrst0}
set -x

# Make sure we start at the beginning.
mt -f $T rewind

# Segment 1 is the tapeboot program.
dd if=tapeboot of=$T obs=8k conv=sync

# Segment 2 is the ramdisk kernel.
gzip -d -c netbsd-rd.gz | dd of=$T obs=8k conv=sync

# Segment 3 is the miniroot image, unzipped!
gzip -d -c miniroot.gz | dd of=$T obs=8k

# Done!
mt -f $T rewind
