Thanks for the fast reply! :-)
I suppose in theory, an internal-type drive in an enclosure would be
plausible, but by the time you get to that, and the rarity probably of
even enclosures for something like that and the added drivers, it
defeats the purpose. Oh well... Worth finding out! ;-)
On an alternate route, I wonder if Colin could create a small PC
program that would allow transferral of .dsk files to the allocated
slots on a Trinity formatted SD card? Though again, I have no idea how
plausible, as it would depend on the way the Trinity formats and
stores things on the SD card.
Obviously it wouldn't make sense to have Sim Coupe emulate the
Trinity, as the point is to have a device that people want to buy
because it allows their SAM to do something they can't possibly
emulate. But a .dsk transfer utility to and maybe from the Trinity SD
cards might be useful? Just thinking out loud! ;-)
Then again, a completely nutty route... Since the Trinity will very
possibly have FTP at some point, file transfer could be done in a
round about way, by uploading or downloading files lol! So in theory,
if you don't have a handy built-in floppy drive, you could develop in
Sim Coupe, upload to your website, and then download to the Trinity.
Sorry Colin, my ponderings are jumping all over the place lol! ;-)

The USB Floppys have a extremly cut down controller which is missing ability
for low level access. So the answer is no. My Acer TM312T has a external
parallel port Disc drive, and it can read and write Coupé Discs, only
because the BIOS. It would be possible to make a USB Floppy which can use
SAM discs, but not in a standard way. And it would also need new drivers.

Just as a side issue, with regards to Sim Coupe... (sorry for the quick
change of topic!)
This is probably a daft question, as I think I've read about the issue
elsewhere, so forgive me... but is there no way to read/write to external
USB floppy drives? Just thinking of my own case, and others are probably
similar, where I use my laptop 99.9% of the time these days (and of course
modern laptops don't have a built-in floppy drive.
Not to mention, there are increasingly fewer desktop systems that include
floppy drives these days anyway, so even people using desktops are
increasingly likely to find it easier using external plug-in drives.
Is it a complete impossibility? ;-)

If SimCoupe uses rdtsc without setting the CPU thread affinity, there are
issues on some systems where it loses track when the thread is scheduled

use QueryPerformanceCounter.
It did use QPC, but only for sub-system profiling within the emulator.
That was becoming increasingly meaningless with multi-core systems, so I
stripped it out a couple of months back! Knowing the running speed and the
framerate should be more than enough for most users.
I remember taking special care of the issue in my floppy driver, where
even kernel QPC could use up using different timestamps on some systems
