PDP-11/23 deskside machine -DAMN

I have formatted a number of MFM ST506 drives (e.g. ST-225) with an RQDX3
on my Qbus PDP-11's. Be careful to set the drives on address 3. I used the
maintenance program ZRQCH0.BIC. This maintenace software is available on
floppy disk.
 I boot a XXDP+ disk image from an emulated TU-58 on a PC running the
emulator program from Sytze Zijlstra This emulator is also very useful to
transport data between PC and PDP-11.
