This might be an answer as well as a question ... ;-)

I once heard that 16 Bit transputers behave different compared to the 32bit types when booted from link.

Somebody told me that they need to get a 15bytes long message , something like a magic word, etc. to boot correctly.

I have this message somewhere, but maybe somebody who knows about that could comment on it.

At the time of saying, however, only the 222 was there.
