Easy answer: A 1024 x 512 pixel display in 16k colours like what for example the Q40 has is going to need a sloppy 1.5 MB of video memory - Twice of what the Trump card can provide. High colour, hi-res GD2 graphics simply won't work in the address space of a 68008.
Beyond that, the poor 68008 might run into some severe performance problems shoving that many screen bytes around.
Even if you'd go back to palletized colour (256 colours) like the Aurora, you still need 512KB, which wouldn't leave a lot for programs.
256 colors and 512x256 resolution cost you 256kBytes, and the 8-bit colour mode is even simpler (faster) to handle than the QL native colours. That could just barely work.

It wil be a very big new features...if a day can be putted this great graphic mode on the GC + Qubide clone card too

Exactly. It does not need to be related to the actual project (TrumpCard + Qubide) but may could be done with a future expansion card which has more processor power, address space and memory.

Do you mean, like a Super Gold Card or Gold Card?

Great news - Rich, do you have a price tag?

Looks good!
I might buy one or two once available.
Adding a QIMI compatible mouse port and battery backup for the RTC would be perfect. Plus a jumper to switch power source 9V/5V.
QL forever!

Thank you.
I think about Minerva ROM ( fitted to interface ) and RTC ( or this is impossible ? ).
Do anybody have the Minerva MKII RTC schematic ?

I have asked Tony Firshman for the schematic for the RTC - but he does not have it and thinks it may need to be re-engineered from the PCB ....
