i've set up a page with howtos, images, and connection diagrams for the following controller-less displays:
    Seiko G648D
    Samsung 0150Z
    Toshiba TLX 1342

link: http://sourceforge.net/apps/trac/serdisplib/wiki/SvnDriverUsbOnethreesevenohoh

focus is on serdisplib but wiring diagrams and descriptions might be interesting for other projects, too.

Thanks for creating that page. It can be very useful for setting up displays.

While reading that one thing that I noticed that might not have been very clearly mentioned in the USB13700 documentation is that the board also supports clock frequencies smaller than 2.73 MHz. The divider is not limited to values 1-10 and frequency range 15 MHz - 2.73 MHz but the divider can also be a larger value resulting to a smaller frequency. The limiting factor is the 8 bit value used in the protocol for transferring this setting. Just thought I'd mention this even if that small frequencies probably aren't normally used.
