; bjp   modified to assemble on as80 assembler (needs different syntax).
; minor mods to account for changes in interrupt structure  and I/O
; all such are flagged with my initials.....
;
; The origional code used operators <   and  >  on symbols to extract the
; lower and higher bytes respectively.   It appears that as80 has no equivalent.
; I have hand coded such ---- hopefully correctly.
; This is only a significant issue with such constructs as 
; My solution forces the stack to remain in its present location.
;
; WARNING   If you must move the stack  --   check comments and fix code for my kludges
;
; Origional Code also had a pretty strange "passed" macro.  Removed it and
; output a more useful message. along with the bist controls
;
;z80 simulator test routine
;total error count is left in a at end of test routine
