I once had such an eprom myself... I may still have it somewhere, but
we never got a chance to use it.
One of the protos I have from way back when is a suitcase pdp-11
with TU58s as the system device. Since it had originally been
designed for use by Field Service, it ran a different set of
software than any of the traditional OSes, and so used an entirely
different EPROM on the TU58 interface board. In order to boot RT,
I had to remove that old EPROM (which I believe I saved, somewhere)
and installed one from a regular TU58 board...
