RX50 / RX33 Questions related to PDP-11's

OK, I've got some more questions. It seems I've finally got the PDP-11/73 I'm working on to talk to the floppy drives. BUT, it won't boot my RT-11 RX-50 floppies. I'm using the RQDX3 controller as the floppy controller and the WQESD (ESDI) controller as the boot device. When I tell the system to boot from DUB0 or DUB1 which is the terminalogy that the WQESD controller expects (figuring that out, i.e. reading the manual took longer than I want to admit) with a RX50 attached, it will access the floppy drives, this is best evidenced by my using a cleaning floppy in the drive (made it easy to hear the drive being accessed). When I try using a pair of Teac floppies I've converted to RX33's using information I found on Sunsite I'm not really sure it tries to access them. How do you cable RX33's? I set them to Drive 0 and 1, as the docs said, and then used a Y-splitter for the power with a standard PC floppy cable (do I need one without the twist?). Can you use RX50 floppies to boot a system with RX33 drives? Will RT-11 boot off of a floppy drive at CSR 17760334? I've tried with both the Boot disk from my RX50 distribution set, and a RX50 boot disk that I made using PUTR. I've a sinking feeling that having two disk controllers is confusing RT-11. Is it possible to create a Bootable TK50 with RT-11 that can be used to do the install? Zane | Zane H.
