That is true, and in fact I have done that successfully myself for open loop
commanding. The problem with the bit banged routines comes when trying to
receive because you tie up the processor.in a wait loop. Driving the EA display
I don't try to receive the serial handshakes coming back from the KS0073
controller either. The data sheet defines the time required to execute each
instruction. I just put in short wait loops of the few tens of uS to make sure I
don't overrun the display execution.

Where are the instructions for posting files to the board?

hey everyone thanks for the help!!! I figured out how to make the
display work. I still have more to do, but I can send text and
variables and call up the saved screens.
