+ - NON-CRITICAL: watchdog logic (triggered after 108 ms without interrupts on original machine) still does not work as intended.
Timer is reset by TWO sources: the VERT INT L from the DC012, or the MHFU ENB L from the enable flip-flop.
The MHFU gets active if the 8088 has not acknowledged a video processor interrupt within approx. 108 milliseconds.
BIOS assumes a power-up reset if MHFU detection is disabled - and assumes a MHFU reset if MHFU detection is ENABLED.
- Therefore a 'warm boot' within MESS (F3) causes ERROR 16.
+
+ As there is no reset switch, only a limited software reset exists on a real DEC-100 (CTRL-SETUP within SETUP).
