[comp.sys.mac] MacII High-Res Video question

fjo@cbnewsc.ATT.COM (frank.j.owen) (03/01/90)

I have just read the latest release of Tech Note #144, and it
implies that the new High-Res Display Video Card has pinouts
identical with those on the On-Board Video (OBV) of the Mac 
IIci. I have 2 questions:
    1) What are the other possible ID combinations used for?
    2) The IIci can support the Portrait display. Does
       the new High-Res Display Video Card ALSO support
       this display?

I'll bet that the hardware of the High-Res Display Video Card is
very similar to that on the OBV. The hardware probably _could_
support the Portrait display, I just wonder if the firmware 
support is there.
