I have a H9273 backplane with the current card configuration:
LSI11/2 | (empty)
32Kwords 18-bit MOS memory | (empty)
4-port serial card (M8043) | (empty)
BDV11 Terminator Card
The LEDs on the BDV11 show that the bus is hung when I power the machine
up. I've tried moving the BDV11 up to the slot just below the serial
card, but that doesn't help any.

Thanks! I'll ask if I can't dig it up.
