Bugs/Features of ispy (version 2.31 onwards) and mtest (version 2.10 onwards)
 
LARGE NETWORKS GIVE 'check links' ERROR (Found in 2.31, Fixed in 2.33)
 
A problem was reported where large (4 * B042) networks gave spurious
"check link connection" errors. Appears on PC and Sun. Failure appeared
to be occuring after the 128th processor.
 
Source code error found and corrected in version 2.33 (22nd Feb '91),
believed to be ok, but not yet tested on a large network.
 
ISPY DOESN'T LIKE BAD .map FILE (Found in 2.31, not yet investigated)
 
A particular .map file was duff (broken) in some way. Using it as input to 
ispy caused ispy to say no transputers found. Reconfiguring and regenerating
the .map file solved the problem.
