I wish to apply the Error pin of a slave T805 to the EventReq of a master
T805 but I am unsure as to how to go about it. 

The hardware consists of a Quintex Fast 9 board for PC x86's. The
Transputer Databook (2nd ed.1989) states that it is possible to
determine when an errant transputer has stopped. The manual states that
this can be done by daisy-chaining the ErrorIn and Error pins of a number
of slave processors and applying the final error pin to the EventReq of
"a suitably programmed master transputer".  The master transputer can then
take appropriate action when a slave processor halts. There is no mention
of exactly how I can apply the Error pin to the EventReq channel. On the
Fast9 board there is a DownNotError pin, from what I can gather,
corresponds to the error pin of the last slave processor. I am unsure as
to which pin (if it is done this way) the EventReq channel corresponds.

Any help is appreciated,

Aaron.
