What are the two DSLRs with fixed lenses?

There was another fixed-lens DSLR too – the Pentax EI-2000 (HP PhotoSmart C912).
Pentax showed an improved EI-3000 version, which I didn't realise was ever released, though one sold on eBay in 2013 for US$50.

Yes, we had one briefly, years ago, and I seem to remember it was quite a nice camera for its time.

How did the translucent mirror effect high ISO performance...by the standards of 2001, that is?

According to the review on this Web site, the Olympus E-10 takes "2 x Olympus Lithium CR-V3 (supplied) or 4 x AA batteries (NiMH recommended)."
You can buy AA-size lithium batteries, so maybe he tried using four of those.

I still don't think there is.
There are SLR's/dSLR's with fixed "mirrors", (also ala pellicle), and dSLR "style", (w/ pyramid where prism would be), to simply "look" more professional and SLR looking.
The E-10, E-20 where and now the RX-10 and FZ-1000 are these.

The e-10/20 doesn't use a pellicle mirror. It uses a split prism system for the optical viewfinder. Splits the image from the lens to the sensor and viewfinder simultaneously. Which incidentally allowed it to be an optical viewfinder camera with live view to the sensor and viewfinder. I think if you want to be absolutely precise it isn't a "reflex" prism but it's far more like one than the fz1000 or rx10 cameras. These simply use an electronic viewfinder. Totally different aside from body shape and having a lens affixed permanently. Google the e-10 and look at an exploded view, it's pretty interesting system.

DPReview describes the Olympus E-10 as a DSLR. Using an optical viewfinder, you look through the lens that is going to take the picture.
Yet there is no conventional mirror. A (D)SLR would have a reflex mirror that swings up and down, to choose whether light goes to the viewfinder or the film/sensor. A DSLT would have a normally-fixed semi-translucent ("pellicle") mirror, to simultaneously send some light to each place, at the expense of brightness.
The E-10 "features a unique prism for splitting the image the lens is projecting simultaneously between the optical viewfinder and the CCD." So it's doing the same job as a (D)SLT, just with a prism instead of a pellicle mirror.
I am not certain from reading the review whether the viewfinder uses a pentaprism or a pentamirror. Just that it is an optical viewfinder, and that the camera has the ability to simultaneously display an electronic preview (what we would now call "Live View") on the main LCD screen.

If you accept that the beam-splitting prism satisfies the definition of "reflex", the E-10 has the rest of the attributes (digital, optical viewfinder that sees through the lens that will take the image, fixed lens) to qualify as a Fixed Lens DSLR.

still irrelevant. With or without prism, battery life is a separate issue to fixed lens.
The camera may have interchangeable lens and very low battery life. Such limitation is NOT Unique to FIXED lens DSLR.
I thought it would have been obvious that I was just posting a schematic diagram including the "reflex" design of the E 10 and not a comment on batteries or anything else.still irrelevant. With or without prism, battery life is a separate issue to fixed lens.
