Yep. I backed up the RD52 in a new-to-me MicroPDP-11 and it took hours. > Be advised, it takes a *long* > time, even on a 11/73 with the serial port turned up to 38400 bps. Has anyone done any console serial port hacking for speed on Qbus or Unibus? On something integrated like a KDF11-B it might not be so easy, but maybe a DLV11J or a DL11W? I'd think hitting 115200 would be really sweet, if everything can keep up. Totally worth some experimentation to see what part gives out at ludicrous speed. -ethan I have not yet had time to build/test it, but a few months ago there was an RL01/RL02 emulator project on VCF. You need a PDP-11 with RL11 controller. The RL0x emultor connects to the RL11 just as an RL01/RL02 disk drive and you can assign it any drive number (0 - 3). But what is really nice is that the emulator cooperates with real RL drives. So, you can have one real RL0x drive and up to 3 “emulated” RL drives. The storage is a flash card. The RT-11) command .COPY DL0:*.* DL1: works (where #0 is real, and #1 is flash). After the copy you pull the flash card and copy it on a PC.
