X Window server for NEC 7220

Hi Does anyone know of an X Window server implementation for the NEC 7220 GDC? The chip has several names including the Intel 82720, NEC 7220A, NEC 7220D, uPD7220, uPD72020, etc. Essentially this graphics chip was the main rival to the MC6845 prior to the domination of the IBM PC architecture for microcomputers. The NEC 7220A is most notably known for the NEC APC and Epson QX-10 however was used in a number of other systems. Typically it was used for CAD type graphics and/or business graphics as its main strength was drawing primitives like lines, circles, rectangles, etc rather than BITBLT operations. I would imagine an X Window server for the NEC 7220 would suffer in comparison to today's graphics boards. However I think it would be comparable to non-accelerated VGA and/or VESA modes which both have X Window server implementations. Thanks and have a nice day! Andrew Lynch, 73 de N8VEM
