requested: hardware information about the TMS9938 VDP chip

Does anyone have some information about that chip?
Register/display memory usage would be fine. I'm especially interested
in how graphics cards for the TI-99/4A using that chip are programmed.
I need this to implement 9938 features into my TI emulator. Several
people suggested not only to use the standard 9918 graphics but also
support the 9938. No problem for a VGA card, I think, but without any
information I can't get it done...

Thank you for support,   Thomas         iws9012@eva.fmi.uni-passau.de
