My second interface designed for the RC2014 and compatibles is a graphic OLED display. Utilizing a 128x32 pixel monochrome (green) OLED display it provides a quick and simple way to add a screen to your setup, easily controllable as an I/O device with jumpers to set the base I/O port.
I decided to go the OLED route rather than LCD as there are some nice very benefits. There's no backlight or contrast issues. More importantly, instant transition of pixels from off to on and vice versa, rather than the often very slow (and too blurry for animation) response time you generally find with small LCD modules.
A graphic module also gives far more scope in terms of possibilities and uses than an alphanumeric display. Supplied built ready to go, there are code routines for initialization and drawing on the display.

Thank you
Quazar continues to produce excellent RC2014 expansion boards. And, communications were excellent when we had to sort out a delivery problem with the USPS.

A beautifully crisp display
One thing that I've noticed, is that it is actually impossible to take a decent video or photo of the display so that it gives it justice. The speed that the pixels transition between on and off is incredibly fast, so there is very little (if any) blurring during fast moving animations.
The board comes with a decent user guide, with Z80 assembler routines for initialisation and display, to allow you to program it straight away without having to understand the OLED controller datasheet.
The OLED display, itself, seems to adapt itself lovely to scrolling applications, but I've found that blitting an image to the display works well, if experimenting with bitmapped graphics and animations.
