[Coco] CoCo 3's CoCo 1/2 mode

I read that when Bit 7 of &HFF90 (cf.
http://www.cococommunity.net/socks-gime-register-reference/ ) is set, the
CoCo 3 is then in CoCo 1/2 mode.

 

I don't have a physical CoCo 3 to check that on (I only have a CoCo 2).

 

But in VCC 2.1.0d I notice that, immediately on startup, &HFF90 contains
&HCC (1100 1100 binary).

 

So it's already in CoCo 1/2 mode? Am I missing something?
