About the same time period Anzac was making many different DBM's.
Most were in 8 pin Hudson can headers and I do still have a catalog.
If you can come up with some specs and pin out I might be able to match
it up and then make some inquiries among my old peers. The devices were
also custom packaged for a few discrete customers.
