Please don't
confuse. The linked picture shows a series 400 machine.
The 715 is an entirely different line of machines. The 700-series is
PA-RISC based, where the 400-series is m68k based. You can run the
original 4.4BSD-Unix releases from the CSRG on a 425t also. (In HP-UX
mode with HIL peripherals.) The Domain/OS vs. HPsUX "switch" is a
setting in the boot monitor, no hardware switch.
I am not trying to be confusing. That's legitimately the unit I have. On
the front it says, HP Apollo with a sticker "Model 715t/33." On the back
side it says A1630 425t. It has an Domain keyboard port and an HP-HIL port.
So what do I have here?
I think that only opening it up will tell you that for sure.
Here's the fronts from a couple of TNMoC's Apollo 400's:

... is the case-front decal on your machine as recessed as on those? It
looks in your photo as though it perhaps isn't - which might mean that
someone has stuck a 715t decal over the top (from memory, they're certainly
about the same size). Of course if that's true, *why* is an interesting
question :-)
(The blue LED on the TNMoC system is an oddity, incidentally - IIRC the 400
was circa 1990, which seems a little early to see one as a general-purpose
indicator on a computer. I think the other 400 in the pair had a more
conventional green or amber one. I'm surprised that someone went to the
effort to replace it, though, and it's not as though LEDs fail often and
force replacement!)
