Wow, the members here are SO helpful.  Especially being patient with a 
newbie like me.

Well, the next problem is getting my LCD working.  It is a brand new 
optrex dmc-61230.  I have it hooked up for 4 bit parallel.

I have it all wired up and all the wires are going to where I think 
they should, but it is not working.   I have triple checked the wires 
while looking at the datasheet for the LCD.  Power wires are right.  
The 4 active data pins (DB4 thru DB7) are hooked to the pins I have 
assigned to bits 0-4.  RS, RW, E are hooked up aproperly as far as I 
can tell.  But I get nothing.

When you power up an LCD should it do anything visible without any 
connection other than power (+,-) and the "LCD drive" which is 
supposed to be in the neighborhood of 1/2 VDD?

I am getting nothing.  The backlight does come on....

No lettering or anything.  As far as I can tell, the test program 
looks like it is running properly, but I am not positive.

I am devoid of further ideas....
