Graphical LCD question

Hi!
A recent shipment of stuff from the Electronic Goldmine included 8 small, apparently graphical LCD's. They have no information on it, but it does have some part numbers on the back (All in all: "79293 SDI 13-04 S6B0755 H2.80 Reverse U6-09B63-AA B31"). Googling various combinations of these mostly gives nothing, but one part "S6B0755" does come up with a driver chip from Samsung. (http://www.ortodoxism.ro/datasheets/SamsungElectronic/mXsqxqu.pdf)
This looks attractive, becuase it seems to have a serial interface, but the datasheet doesn't give more information on that, more on the display protocol the chip uses. Anyway, the problem is the hardware connection...the LCD's have one if those elastomer connectors with alot of tiny contacts embedded in a piece of rubber. They are so small that I can't even count them. Also, I am not familiar with the package of the chip mentioned in the data sheet ("Gold bumped chip or TCP) First, how would one go about connecting to these, and second, would it be possible to use this LCD with the chip above from a Stamp, and is it worth attempting it...it looks very attractive
Thanks
Rafael

You've got to play the game.
You can't win.
You can't break even, except on a very cold day.
It doesn't get that cold.

The memory also corresponds with the LCD layout, if you see page 16(19 out of 69) of the PDF.
If you use the 8-bit mode you can read back the picture, so you don't have to keep it in BS2 memory.
There seems to be a couple of functions to invert or mirror the picture, too.
(By writing to a special memory location)
