Hi.

Can I use a RLV11 in a VAX 4000-400?

The pdp11-field-guide.txt says:
RLV11 RLV11 Q RL01/02 disk controller option, consists of
RLV11 modules M8013 and M8014. Q/CD-only option.
RLV11 18-bit DMA only. Caution: uses BC1 and BD1
RLV11 for purposes other than BDAL18 and BDAL19

The VAX 4000-400 has a 22 bit Qbus (all slots are Q/CD). So it looks
like this can't work due to the 22 bit bus that uses BC1 and BD1?
