Err, which RLV11/RLV12 emulators are you seeing? I know of several RL02 emulators - Reinhard Heuberger's, and another I can't immediately find my saved info on - (and one crazy project that turned a real RL02 into a USB device :-), but you still need an RLV11/12 controller.
The only ones I can find now are the ones you mention. Yes, I too can't find my notes on the second one, whatever it is/was. I was *sure* that someone had made a Qbus emulator that used SD cards, but I simply can't find any mention of it now. Right now, it looks like Reinhard Heuberger's board is the best bet. I haven't checked with him yet to see if boards or kits are still available. If I could find a working TDL-12 I would jump on it in an instant. All the older ones (Dilog, etc.) appear to use ST-506 type drives, which introduces its own set of problems. Alan Frisbie
