Your libary sounds interesting but....
I have purchased a 128x64 display named JN12864J obviously with a different controller than the KS108 stuff.
Controller is a Sitronix 7920 ([/http://www.dfrobot.com/image/data/FIT0021/ST7920.pdf ]).
Pinout is app type B with main difference that only one CS is needed and NOT 2 (CS1,CS2) as on KS0108.
Would it be possible to use/change your library to this type of interface?
