I had a real-time data collection program running on a VaxStation-I that required that the verticle retrace interrupts from the VCB01 be turned OFF. ( It required putting a scope on the Q-bus to watch the interrupt request lines to discover that this was the problem - the fact that there WAS such an interrupt every 1/30th ( or was it 1/60 ? ) sec. was sort of documented but not very prominently! ) I am trying to port this code to a VaxStation II /GPX . 1) Is this also necessary with the GPX/VCB02 board ? 2) How do I do it / What are the register definitions ? I have made several attempts to order documentation from DEC but nothing I have has the right info. If someone can send me bit definitions for the VCB02 (and the part # of the manual I need ) it would be greatly appreciated.
