Not so sure about that, once tried the latest download
and tried it in my old PI, and it did not even boot.
Checksum was OK, no download error.
Was just curiosity.

Tell you what, if my P4 crashes (is on a no-break supply now running 24/7) now,
so hopefully never, then I will try that Buster in my very old Pi driven wall
clock:

the I/O will for sure not work as GPIO assignments and I/O addressing changed
but maybe it will boot...
Sometime? Do not hold your breath.

Old one:

Cannot even find the BCM2708 in Wikipedia's raspberry list, must be an earlier
model I have?
Lemme google...
Aha!
 google BCM2708
and there is a can of worms...

OTOH I even have a raspi mpeg2? decoding key for it that I bought from the
foundation,

So in short YMMV
