Somewhere I probably have the manual for my Thomson 4160.  It also had the
4-way switch on the front.  I cannot remember now what positions 1-3 did, but
position 4 is the setting I used with my 8088XT.  I can tell you that because
it is sitting right here.  :)  That position allowed for CGA color.  One of
the other 3 positions was some sort of color setting my XT did not support,
and the other two (one each) were for green and amber monochrome screens,
IIRC.  Those settings did work with the XT but I rarely used them.

If I find it, I will post my findings here.  I'd fire it up, but that'd not
really help you figure out what that one non-CGA compatable setting was for.

Mike
