In response to "Is it possible to make a transputer look like it has been reset?
" ---- YES IT IS !


There are two alternatives :-

1) Execute the instruction which puts the processor back into the reset
   state. (I'm not sure if this is documented nowadays, but it's there).
2) Run a program which emulates the peek/poke/boot procedure and then
   jumps into the booted program. Obvoiusly this allows more complex
   things than (1) (like looking for boot code simultaneously on links
   and non-link devices) but has the disavantage of not being able to
   cope with programs which try to boot into memory being used by the
   loader.

We have used both the above with some success.


(Although it looks like it is, this should not be confused with INMOS 
 technical support).
