I have a few of the Alesis Corp. G8 2x16 LCD's and after doing some research, I found there was no documentation available, only groups with questions the same as mine. I traced the pins back to the KS0066U processor and this is what I came up with. Since others were wanting to know as well, I thought I'd post the pinout and maybe save someone a little time.
