Does anyone have experience with interfacing the BS2 to a graphic LCD...

I want to interface my BS2 to a Hyundai surplus graphic LCD screen
from All Electronics. See it at:

I have experience interfacing to a SEETRON 4x20 text serial LCD
screen. I have easily mastered that. However, I want to know how
harder, if any, it is to use this Hyundai display. I know that the
Hyundai is parallel instead of serial. I think it's possible to use
a shift-register to convert serial from BS2 to the parallel for the
LCD screen. So, what kind of code and/or electrical work am I
looking at. How difficult in comparison to the 4x20 LCD is this?
And how simple is it to access the graphic functions it has (to draw
some lines or circles or points, etc.)?

Hi Jacob:
I have some experience interfacing the Hyundai 256x128 graphics
display to a BS2P MCU.
I have been using it in the Text and Graphics modes.
The only problem is that that to display graphics data, you need a
large data space (8,000 bytes or more).
I can give you some examples. Please conract me at
