There's a color graphics lcd controller (ic8),
a tft lcd interface (ic6),
a tft controller (ic1, 7),
a tft color lcd
I think that it runs like a TV ("ntsc/pal video chroma", ic16) really.
It accepts external video source (J4)?
The cpu (ic10) has 19 address lines (a0-a18)
and 7 data lines (d0-d7) going into that IC8
It's interesting the front panel buttons - (8) pull resistors down to ground, 4 buttons to one input and 4 into another; must be doing like an analogRead (!!) there.
There's a rotary encoder for "vdial"
It's possible that, if you know how the menus go that you could pop the buttons to achieve, along with an external freq meter, some functionality, but trying to pick out the address and data to find the current FREQ data alone would be difficult.. very, very difficult.
