Q22 disks existed on MSCP, of course. And RL02 also,
if I remember right.
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).
