The camera you seek isn't an Isometric camera. 'Isometric' traditionally maintains the vertical lines but receding faces slope off at 30 degrees to the horizontal. Instead what you're after is a PLANOMETRIC view where the front face is shown flat on while receding faces are at 45 degrees to the horizontal.
I've been mucking about with Maya for a while now trying to recreate this camera but I doubt it can be done because the planometric view is essentially an optical illusion and, by its nature, distorts the objects being shown.
Planometrics is a trick of 2D and can not be solved by checking ORTHOGRAPHIC in the camera's attribute editor because it's not an orthographic view, unlike ISOMETRIC which is.
Maybe you could achieve the effect through compositing in a 2D program. Render the FRONT view of the object and composite it over an orthographic 45 degree shot. You'd have sizing difficulties though since the front view would be larger but with a bit of tweaking it could be done.
