parallel LCD''s PITA

I did hook up the contrast. I do have control of it. But am not
certain where it should be. Should I have all the "blocks" across
line 1?
With enabling Line 2 shouldn't these blocks appear there as well?

As far as being Hitachi compatible....all the pinouts/labels are the
same so I assumed as much (insert *** jokes here!).
The controller is listed as a KS0066UP-00 which on the datasheet
seems to match the few examples I've seen.

Am I right with the OUTh for outputting data?
I've set pin 8-15 as outputs and p15 is connected to p15 on the lcd
(D7).

My local suppliers seem to want to charge $90 for a serial lcd. I
didn't appreciate the guys....consumerism/capitalism??
Anyhow, list prices off the net (although in US) are considerably
cheaper....almost after exchange rates....

I did go and pick up a serial to parallel IC as a plan later. I'd
love to be able to get this working cuz this one only cost $20.
