don't worry, this reply continues the off-topic discussion, but then
"RTN" on-topic.

That is an absurd comparison.

The prospectus is completely confusing, it claims that the 520 ST comes
with 1 MB main memory.

My original Atari 520 ST user manual mentions 512 KB RAM and 192 KB ROM,
where the manual's "KB" is for KiB. IIRC software, but without doubts
the manual and related books use base 2 without any rounding at all.

I doubt that the rounded off name should fake to provide 520 KiB, nor do
I think that it does confuse. I dislike it anyway and guess 512 would
have been a better choice for the name.

Here is a photo of my Atari 520 ST: https://i.imgur.com/lx5pucp.jpg
You might notice that the original 512 KiB are replaced by a (4 MiB) PC
RAM bar and a few cables. If you zoom in, you might notice that it has
got a 80268 CPU (in addition to the original MC68000). Unfortunately
it's more or less impossible to add a blitter to the 520 ST, but TOS is
replaced by a later release, too.

I don't have seen a lot of Atari ST, TT etc. without modifications, but
probably thousands with modifications, most of them for sure with a
hardware QL emulator. It was another time when we used this machine and
other than the Amiga, the ST was mainly used by what we might call
nowadays "nerds". Most of them for sure QL nerds. Another that large
group often were "ordinary people" who were musicians, but probably with
friends like me who were musicians as well as "techies" who again had
other friends who were "techies", too.

Apropos emulations. The OP wrote: "I created a 6g QEMU image."

"Ordinary people" unlikely will use QEMU. IMO handling "space" used by
emulations is more easily done by taking care about base 2 unites, than
base 10.
