If you look at IBM documentation (especially the BASIC

Looks like the network around Q204/Q205 is the dark-yellow to brown
translation in the IBM CGA montor. I can scan that part of the circuit and
post it if anyone's interested.
I haven't checked, but wasn't there also special-casing in the EGA BIOS
code to handle the dark yellow=brown case?
