Very nice indeed !

That looks really nice.

The ability to output direct composite video for CGA is the only thing not present that I would have liked to see on something like this. To be fair, I can imagine why that might have been deemed out of scope for the envisioned use cases.

looking good!
regarding the composite output, I believe it is already supported

here's a photo of my screen : Doom, with the on screen menu, scanlines set to 1/8
on screen menu is operated by a button on the bracket, or button connected to a header (you could use your turbo button or reset button as well if you like)

Awesome!

Video memory: 256 KB, 320 KB with the VESA modes

How do the VESA modes allocate the extra 64 kB on an 8 bit card? Is it taken from system memory?

No system RAM is used—it dedicates 320 KB of the RP2350’s internal SRAM for video, when needed.

I meant to an actual TV/monitor with composite input.

Is that what you meant ?

that is not supported, it is composite emulation on hdmi
the card only has hdmi output

It's not often you open up the store page and the product costs less than you thought it would be

Here are some photos of Serdavision in CGA composite mode, on my XT computer

Space Quest 1 :

King's Quest 1 :

Here you can see the settings used for KQ1 composite :

Some testing with Alleycat

Given how much interest there was in the CRT terminator, I'm honestly surprised this hasn't been getting more traction

You say 9x16 vs 8x16 or height 8x8. Text mode.
So it has MCGA text mode?

This board has been living rent-free in my head for a while and has given birth to a build idea.

So, if I do buy one, it will likely be for a "ship of Theseus" type build where I would want to combine it with a PicoGUS and as many newly made plugin substitutes for old hardware that are designed to conform to older standards and as few actual vintage/retro parts and components as possible and keeping it as modular as possible (everything in a single FPGA or running in emulation on an SOC would feel like cheating in this case).

That's a cool idea. I can't say I've ever seen anything like that before.

I can't afford to build such a thing any time soon, but my mind is going through all the possibilities now...

A modern-built retro motherboard (maybe something like this).
Some kind of hard drive sound simulator, like this.
GOTEK for floppy and maybe an IDE\CD emulator as well.
SerdaVision HDMI for video
As many modern ISA sound cards as you can find.
Put it all in a Silverstone FLP02.

... would be a very cool project. 😀

Yes: 8x16 (640x400, as MCGA) is the default, and 9x16 (720x400, as a real VGA) is a possible setting in the latest firmware.
so both are possible

All I need is time and money.

The former is harder to source than the latter.

now also VGA 9 dot font is supported,
and additional 'phosphor' color 'plasma'

I have been playing with the new fw on my beta board, it works very well 😁
the plasma and amber modes bring back memories...
