ncurses you can fix by adding the new format to terminfo, if even remotely similar.  Then, you just set the TERM environment variable naming the entry.  Not everything needs to be ANSI/DEC/VT/XTERM compatible...

I think your best bet would be Realtek RTD266X, considering it is used by Adafruit and Pimoroni for similar stuff.

Getting hold of sufficient documentation to implement the board and program the darn thing will be the biggest hurdle, I believe.

for now, as application, we only have a test-bench and a text-editor (like Nano/Joe), both linked to a custom library that manages the vt-term at the low level.

Yup. I'll try to buy some chip, and boards, then study the doc, and see how it goes  :-+

They are called scaler boards, basically the same thing as in a monitor.

The GenesisMicro ICs do have an 80186 as their embedded controller. Others tend to use 8051 or 6502.

Ah-Ha!!! I knew that thing smelled too much like CPU/MPU.
In one of those monitors, someone sticked a "intel-inside" sticker

and guess what? I bet there is an 80186 inside, LOL  ;D

(
x86 haunts me, the more I try to stay away from it, the more I find it under my feet
under my desk (Geode thinclient) .... inside the weather station (80186), inside the NAS (i5), and now, even inside the monitor!!!
one way or another
