Hi Michael,
I am not sure. Your guess is as good as mine... I think a lot of them, are probably pulled high internally.
I have found that some displays don't work reliably for me, without using the reset pin. And I have done a few boards I played with, of tying the reset pin of the display to the processors reset pin. So each time the board resets, it causes the display to reset as well, without tying up an IO Pin. If I remember correctly I first saw that on one of @Frank B's boards.
Ok. What I'm doing is soldering up a prototype board that I can plug in one or two 10 pin 5x2 IDC cables to connect to the different displays (having a different prototype board to connect to each display), and I figured I could use a 6 pin SIP resistor network to simply provide the pull-up for the CS/DC pins. I will just clip the pin for the reset, while providing the pull-up for the CS/DC & extra 2 CS pins.
