If you don't mind a toggle-in (err, um, ODT-in) bootstrap, you can
find a selection (some of them with disassemblies) at

 http://metalab.unc.edu/pub/academic/computer-science/history/pdp-11/

just click on "Bootstraps".  If you really insist on rolling your
own from scratch, you can burn these (modified if you want) into your
own EPROM's.

Chances are that if you find a Q-bus card that takes EPROM's it will
already have a boot ROM in it.  For more on what's out there, read
Micronote #3 "Compatible Bootstraps for the LSI-11/73" and Micronote #15
"Q-Bus Hardware Bootstraps".  If you don't have a printed set of
Micronotes handy, you can click on the above link at metalab and
then click on the Micronote index.

The UC07 has an onboard PDP-11 bootstrap you can enable.  Why not just
turn it on?
