Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

That's very good! Much better than what I'm getting on both my 15" and 17" LCD monitors. What native resolution is that LCD?

  Gadget said   just to experiment i played with the timing and managed to modify the display to have 8 bit wide characters giving effective resolution of 640 pixels across only issue is that the display didnt use full width of screen but it looked very clear.


Good work! I thought it would make a difference. 640 resolution is good, an even multiple of 1280 (17" LCD= 1280x1024).

  Gadget said   at this stage I'll leave it as is, next step is to include a TRS-80 like character set for chars 128-191 then make the last 64 characters programmable. lets see what transpires.


Whoo Hoo! Programmable Character Set for the MM! You're a legend! :)Edited by Nick 2011-07-02

Hi Nick,
Just had a look at the NEC LCD and i was wrong about the screen size. It's actually a 17" 640x480 screen Model NLT-17C.
Its easier to ask forgiveness than to seek permission!

And 12 VDC input, so I'll be able to use it in a non 240 VAC situation

I used to be a great Sparky, now I am just a Nerd.

Sorry Matthew,
I keep reading your signature and admiring it.
It reminds me of days gone by, in fact back to 1964, 47 years ago. My first business venture.

17" and only 640x800? Wow! That is very low res for that size.

UPDATE: I looked it up. It's not 640x480. It's 1280x1024, the correct res I expect to see for that size.

Thanks for that Nick,
When I power up the screen in flashes the resolution up on the screen, with the Maximite plugged in it comes up with 640x480.
Funny that when I used it with my PC it had crap graphics quality Go figure!
