They will now. Also the Raspberry Pi Zero.

All I did was to recover the ability to set r8g8b8 mode on 9pi, after
a firmware change broke it. I don't know whe

Probably a typo, I was going from memory. I thought it was a multiple of 8
bits per component, not for the whole thing, so that (and a typo) would
explain it.
But the bigger problem was that even if you only have 1 bit for r, g, and b
you should be able to represent yellow as 110, so any r>1g>1b>1

OK, new 9pi and 9pi2 kernels in /n/sources/contrib/miller should now do
the right thing for 24bpp

Yes, someone on the netbsd mailing list noticed (Jan 2015):

You can set the screen depth to 24 on the pi instead of the default 16.
Set vgasize=WxHx24 in cmdline.txt where W and H are your screen dimensi
Well, that led me down a rabbit hole where I found two problems and now I'm
having a third that I need advice on. The main problem was that I was
forgot to set the draw op to src when doing the final draw of the window,
so it was defaulting to SoverD. Second, unrelatedly, the alpha masks were

If you are talking about DVI, you can use something like this (without loss):

I'd check that the image you're drawing with S over D isn't filled with a
completely transparent value
if the image has got an alpha channel.
jfmxl, this mailing list is not a hardware store. how are we supposed
to know what "digital plug-in" means?
if you still have the package of your TV or the manual it might give a
hint. Otherwise I'm sure you know how to google.

Do you suppose Pi 3 may have fixed the 'sub driver' bugs? What's a 'sub
driver'? not 'usb driver', or is it? The audio out is broken, but it's
your fault? How is that?

hence hdmi to DVI adopters are very cheap.

That's exactly what I'm doing. I don't have a monitor with HDMI within
network-cable and power-cable reach to hook it up to, and the last time I
hooked it up to my TV my toddler tore the usb/power cable of the Pi in two,

Either I'm going insane, the default Plan 9 /dev/draw in-memory
implementation
doesn't implement draw(3), or possibly both.
When I do the following, it works as expected under both drawterm and a
locally mounted instance:
1. Allocate a screen with an 'A' message
2. Allocate an image on the screen
