The fact that the machine hangs solid when the card is
where it's
supposed to be may be a clue that the it's permanently stuck interrupting.
Depending on backplane the grant may not endup where you guess it is.
My memory is fuzzy on this but I think Ht-11 (heath os) did not like RTC
<line event> interrupt and would hang on that.
Does the Heath machine at least have a
"halt" button so you can
get down to console ODT ("@" prompt) and do further debugging from there?
Yes, also DLV11 or the heath serial card both should have HALT on BREAK
enabled. <both support it as do the 11/03>
