Well, it does :-). Lots of little switches to try. I finally found the combination to get it working. It will not work on IRQ 2; apparently the Model D uses that interrupt for a special real-time clock. In addition, it will not pass the diagnostics (not even the initialization test, I believe) if there is no *cable* attached to the board. Now I can get back to work...
