I've found machine that I think is a prototype

From the outside the case looks exactly like a
Vixen case except that mine
is a ugly brown color rather than the grey/white color
scheme you usually
see and when you open it up it's slightly different from a "production"
Vixen - the floppy drives in mine are horizontal rather than vertical and
the back panel is re-arranged a little. There are no labels of any kind on
the machine except for the giant "OSBORNE" that's molded into the plastic,
and the PCB inside says "Osborne Computer Corp, Rev 2". When you turn it
on, though, it identifies itself as an "OCC 4" and asks for a boot diskette,
so I'm thinking that must be what it is.
I have a Vixen that looks exactly like the one here:

...except that it has no nameplate on the front and no labels in the
back. There are no signs that it ever had them. Mine powers up with
"OCC4 1.04" with a copyright date of 1984, and asks for a disk.

Dave has a set of disks for the Vixen:

They work on my machine.
