I had a look at the video card, it only supports 640x480, right? But the vi=
deo=20
on the TS-7300 "could" also do 1024x768? Is there a technical difference.

And does NetBSD support the TS-7KV on the TS-7200 board?

Does X11 need wscons? If not, would it be possible to simply start X11 on=20
startup and use this (with NetBSD).

When do you think is the TS-7300 fully usable with NetBSD?

Is there an FPGA load available/planned/... that makes such video modes=20
possible?

What video modes are possible with the pre-installed Linux?


Thanks a lot for all your answers,
