I ordered ST7920, but seller sent these instead by mistake. 240x64 resolution. They're on the way, and I'll give them a try once they arrive.
But what I've curious about, documentation mentions built-in fonts, but sample code posted above seems to load own characters, why?

The built in fonts are 6x8 or 8x8 pixels. So they are very small. Most users want different size fonts. The compsys1 pbp code works

Well, common HD44780 based displays have 5x7 font, but no one complains...
Anyways, let them arrive and let me see, what they can do

The pixels are smaller than on a charactor display.

In the text mode you can get 8 lines by 30 charactors with a 240x64 display.

Do you have a datasheet for the displays you are getting?

Hopefully your displays have the built in negative voltage source for the contrast.

Well as seller stated, they only need 5V for operation, no separate negative supply needed. It also has contrast adjustment pot soldered on it.
