Strange Performa 475 (Prototype or early "Dev" model?)

The indents on my case are because it has a manual inject floppy drive like the LC III+ did.
I have another PC475 exactly like yours on the exterior but no reset switch or rom socket but still says primus (assuming Primus isn’t rare at all).

Logicboards sometimes go through a few revisions throughout production. The 475 wasn't manufactured for long but there is definitely more than one variation as some have the CUDA switch and some don't. Some boards are yellow/brown and some are green (perhaps depending on where they were manufactured). A lot of Apple logic boards were made in Ireland but they had factories making them in other places, possibly Singapore I think.

Interesting, also there is some strange software on here.
