Re: [emulatorII-list] Re: EII LCD Display

2010-10-21 by James Ulibarri

Just got off the phone with Tim at Crystal Fontz.    The green is in stock.

http://www.crystalfontz.com/product/CFAH1602A-YYH-JT

Now it seems like it will fit per John's correspondence with them, but the issue at hand is the voltage to the back light.
Tim wants me to have it fit, and basically find out if the back light blows up due to a lack of a resistor on board. 

Now regarding the blue, part number # CFA1602A-TMI-JT , if someone wants that (me !), would have to be built by their factory in China.
And they said they could integrate a custom resistor on board of the LCD for our EII's, to avoid the EII are blowing the back light out.

I don't feel that my tech would even chance sending all 5 volts to it anyways.  He's kinda resistor happy and he wouldn't send a full 5volts to the unit anyways.
He tends to like to drop down everything by 1.5 volts and then start there.   There is an 8 week lead time for the blue units if someone wants those.
I sure do.  Two months will fly by like nothing so I am not put off about that.  But we have to order 10 minimum.  They of course won't just make a one off blue unit.
I don't mind springing for them if the green one fits.  I have one on the way and I'll let you guys know if it fits and how it looks.

The green is gonna look funny, but this is just an experiment.

That $5 Ebay one is the wrong size, PCB outline and viewing area:

Original is 84 X 44 X 11 mm outline, 61 X 15.80 mm viewing area.

I've just been told somewhere else also that the old LCD's were Hitachi HM44780 but replacing with a modern Powertip one of the same size was NOT straightforward but worked eventually with some knowledgeable tinkering and modding.

Think this is a project too complex for me, short of maybe buying the $104 original SP1200 one, although still not sure if exactly same model as the EII for a straight swap. Seller cannot confirm....

Anyway, good luck with yours James, let us know if you discover an easy swap solution in your spare EII ;)
