I have an
Altos 586, an 8086 machine that is completely NOT a
pee-cee. 
 Hm, that might be an interesting question.  What machines are there
 built around x86 CPUs but which are definitely not peecees?
 I suspect there are more of them with the earlier CPUs (8086) than with
 the later ('386, '486, Pentium, etc).  The latest one that comes to my
 mind immediately is Sun's 386i (the "Road Runner"). 
 
    The SGI 320 and 540 are arguably not PeeCees even though they run
 Windows.  The firmware is nothing like the normal x86 BIOS.
