I am making some progress with getting the KMC/DUP emulation working in SIMH for TOPS-20. At the moment I am stuck on one thing, which is the interrupts to tell the OS that the KMC has processed a buffer. The OS sets the interrupt enable bit and when I have something to report to the OS I set the relevant interrupt bit. However, nothing happens when I do that. I am wondering if I have the right interrupt bit? I am using bits 8 and 9 (decimal). I am not sure how to find out which bit I should be setting. Can anyone help?
