DG Secure OS?

[P. Sullivan]

In their ad on page 99 of the Jan 87 issue of
Defense Electronics, Data General Federal Systems
Division says they offer "...Multi Level Secure
Operating Systems...".

I had not heard that anything DG offers, whether
AOS/VS or DG/UX (or any other Unix derivate besides
DG/UX) had been certified and I am mystified by this
claim. Can anyone offer enlightenment?

Kindly reply directly as I am not on this list.

Thanks,
