There is the 2 board RLV11, which is 18-bit, and the preferred 22-bit
single-board RLV12.  I have both.  I started with a BA11-N box in 1986
and didn't mind one bit paying $100 for an RLV11 and taking up two
slots (the RLV12 was still full price at the time).  For any MicroVAX
or a MicroPDP in a BA23, can't beat the RLV12.  I have one in a bag
waiting for me to have some time to build up an RL02 image slurping
box (having recently repaired the line filter caps in a BA23).
