Display for an Amstrad notebook

Other Hardware Displays
1

Hi!

Got an display from an amstrad notebook, NC100.
Big display 8 rows, 80 columns.
Is there any chance to connect this to my UNO?
14 pins with no marking on them.
It has the following number:
JAPAN
CITIZEN
H4062H-PR

Does anyone know how to connect it?
Have search via google but have not found out.

Thanx.

You're probably not going to find much information on that display, if any - given it's age. Did the NC100 work before you pulled it? If so, you have a couple of options:

  1. Put it back together, then stick a logic analyser on the LCD pins and try to reverse-engineer the protocol...
  2. Put it back together, verify that it works like it did, then put it away in a box - wait 20 years, then sell it.

Likely, if you take option 2, you'll probably be money ahead (the NC100 looks almost like a TRS-80 Model 100; maybe it will increase in value similarly).

Your other option would be to try to get the NC100 and the Arduino talking to each other; that would be a pretty cool feat...

If i remember correctly, the display in the NC100 is a "dumb" display - that is, you need to refresh all the pixels at least 20 times a second to make it flicker-free. The display has no memory so you need to allocate 22.400 bits for display memory... That isn't possible with the memory in any Arduino.

Sell the computer to someone that collects them, or start building a display controller with a FPGA or similar.
