Don't fret too much. The OSD works only with the Gotek hardware, not with the HxC hardware. But it needs HxC firmware flashed onto the Gotek hardware (or, apparently FlashFloppy firmware on Gotek hardware).

ADDING AN INTERNAL ULTRASATAN

I have built this bracket to allow mounting the UltraSatan (standard size) to the top of the Gotek floppy emulator


It screws into the Gotek via a M3x20 screw, replacing one of the original Gotek case screws:


And then the UltraSatan screws onto the bracket with a M3x25 (replacing the other Gotek case screw) and one of the removed Gotek case screws (which now screws only into the bracket):


The UltraSatan data cable then plugs into the header on the motherboard, and yes, the top case fits on just fine.


The STL file for the bracket is attached to this post, and is also available on Thingiverse or fully editable on Tinkercad.

That's pretty cool

Nice. It will be interesting to see once these H4’s are up and running and some of us have them in cases etc like @derkom has, how they are standing up to regular usage and everyday life.

Another succcessful 1.44 MB GAL installation. This is a Gotek running HxC firmware. Will test out a genuine floppy drive later.

Nice one @derkom , I've got to try this myself some time this weekend

Very nice!

@derkom Well done. Does the HxC firmware allow you to use Pin 2 voltage to feed to the H4 board?

I do not know. For now I just set up the jumpers appropriately, and unfortunately will now be otherwise busy for a few days, but I'll figure it out when I get back to it.

I've spent some of my extra at-home time building a new version of the internal Gotek+UltraSatan setup, this time based on BRAINCELL's Gotek mount, modified to make most of it flush with the outside of the case, and to add a rotary controller and an external μSD slot, which is connected to the second UltraSatan SD card slot via a SD card extension adapter.

This is what the bracket looks like now...


And with the Gotek, rotary controller, OLED screen, and SD extender attached, and installed in the H4...


Then a little custom mounting bracket to enable affixing the UltraSatan to the stack...


And the whole stack assembled, with the SD card extender's ribbon cable tucked between the two (we'll see if this survives long term)...


Here's what it looks like from the outside, with the case put back on...


And HDDRIVER sees both internal and external SD cards...


Why printed in black? I plan eventually to paint the whole case black. Normally I wouldn't paint an Atari case, but since this is the H4, I think it's okay to do something a little unconventional.

One caveat is that since the extender remains plugged into the UltraSatan all the time, there doesn't seem to be any way to detect card changes in the external slot. Maybe there's a way to get HDDRIVER to fully reset the bus (a rescan doesn't seem to do it), so a power cycle is necessary when changing the card. It's a sacrifice I can live with to have an external SD card slot.

I'm not going to put these models up on Thingiverse because this one is so heavily specialised to my specific setup, but should anyone happen to want them, I've attached them to this post.

EDIT: Modified the US bracket a little bit to make it work also with a slightly older version of the board with different screwhole spacing.
