BS2 and t6963 LCD Controller

Hi All,
I am looking to connect my BS2 to a 240x128 LCD with a t6963 controller.
I am having difficulties decyphering the initialization strings.
I have found some parallel port programs·such as Power LCD, which works, but nothing for the stamp.
Im looking for some help in writing the code to get this display started. There is alot of info out there on the t6963 controller, but it seems that no one has ever hooked it up to a Stamp.

Ive tried to modify the code for the parallel LCD available from Parallax, but that didnt work, Ive even tried to debug my parallel port to see the init string, but Im not very good at that either.

Any help would be awesome!

Thanks,
Eddy

    Hey. I've had this same model for over a year. I've been trying to find specs for it for a long time, and stumbled over your post during the most recent wave of searching. Actually, I found that I purchased the item from eBay user coldfusionx, and that he promised to email me documentation when I got it, which never came. After a few requests through eBay to him, I finally gave up. However, I found the following PDF, which looks like it may help at least with SOME of the legwork. Let me know if it helps you, as I'm getting ready to hook mine and start using it as well.

    Thanks for the reply rockstar_
    I have not had any luck with my coding.
    It seems that I can get command codes to the t6963, because when doing a status check I get appropriate replies.
    As far as sending data, that I still cannot get.
    I cannot place a cursor or send text.
    At best I get garbage on the screen.
    One thing I cant figure out, when sending a character to the display, should I be sending lownib and highnib as the character or would a HEX code be good enough?
    I do get diffrent results when sending diffrent init codes, but nothing reliable.
    Im still doing something wrong.
    Id be more than happy to share my 'work in progress' for others to check out.
    Its a bit messy and a bit long, but I think I have the process right anyway.
