Just had a DS200 open a few months ago, and there was a 68000 in it,
with no PDP-11 of any sort (not even a T11). Also, if you look at
the contents of the ROMs or the MOP download code, they are full of
68K code. For instance, there are lots of hex 4E75 words, which is a
68000 RTS instruction. Shows up as "Nu" in ASCII, or "uN" if your
byte
order is different.
