You should be able to get it running without the DEC panel (I have certainly run M8190 cards in an 11/23 chassis, without the front panel); the serial connection is the same as the DLV11-J, etc, pinout here: http://gunkies.org/wiki/DEC_asynchronous_serial_line_pinout and most of the functionality of the panel (e.g. the force dialog switch) is repeated on the CPU board as jumpers/switches. That turns out to be purely off-board (using a clock on the card, and the 'external clock' option on the CPU (same as the 11/23+). This is the only part I wonder about - I'd have to check to see if there's anything critical in there for controlling the power supplies. Noel
