Paul,
Thank you for that. I enabled the history and then loaded and ran my
initial test program:
1 .enabl AMA
2 000000 .asect
3 014000 .=14000
4 014000 012706 002000 start: mov #2000,sp
5 014004 000240 loop: nop
6 014006 000776 br loop
7 014010 000000 halt
8 .end
And it ran for quite a few iterations through the loop, and then:
014004 002000 000000| 000000 NOP
014006 002000 000000| BR 14004
014004 002000 000000| 000000 NOP
014006 002000 000000| BR 14004
014004 002000 000000| 000000 NOP
014006 002000 000000| BR 14004
014004 002000 000000| 000000 NOP
014006 002000 000000| BR 14004
005266 001774 000014| HALT

Just a wild guess, could this possibly be an unhandled LTC interrupt issue?
