I never ran an RL01 on my RL11 (my RL01 mostly lived on my RL8A, but sometimes ran on an RLV11 in a Qbus box). I've only ever run RL02s on an RL11. > Are there any known issues? None that I can think of. They should be perfectly happy in the same box. They have different CSRs, and different vectors. No possibility for a conflict there. They might be at the same BR level (have to look - it's the wee PCB plugged into the machined pin socket), but if so, that just matters which board is in front of the other as to who gets interrupts first. It's _possible_ there's a preferential order there, but it's not a limitation I recall from the old days. > I found a large box of RX01 disks, lucky me.

You have an RX01 and an RX11 (M7846) not an RX211 (M8256), right? If you have a KM11 or replica, you can use that to debug the RX01. -ethan
