I need to check if the 8088 acknowledges vertical interrupt requests. Unfortunately there are no good examples with this CPU...

There are some instances (Apollo, Amstrad) where a config statement like


is used. Is this the way to go...? It seems i have overlooked a precondition, cause i cant get the syntax right.

P.S.: i want to mimic the VERT INTR L output from the DC012 display controller which clears (or rearms) the hardware watchdog. smile
