RQDX3 on an 11/23?

Jerome Fine replies: While I agree that the RQDX3 is a great controller, unless the user has substantial hardware ability to connect a 50 pin cable to the hard drive(s) with 34 pin and 20 pin edge connectors, I suggest the use of a BA23 box which usually contains the panel for the distribution of the RX50 dual floppy drive and 2 MFM hard drives - although the front panel normally has buttons (READY / WRITE PROTECT) for just one hard drive. The BA123 box usually comes with the distribution board to handle the same RX50 floppy and 2 hard drives or up to 4 hard drives with no RX50 floppy - although you also require a SEPARATE assembly for the READY / WRITE PROTECT buttons for EACH hard drive. Being a person without hardware ability, I always choose the BA23 or BA123. These days, the hard drives might actually cost more than the SCSI host adapter (controller). The "nice" part about a SCSI host adapter is the capacity of the hard drives which can be 4 GBytes for very low cost - a few dollars. ESDI controllers are also now very inexpensive, but at least ESDI hard drives are also very large (600 MBytes were standard), but might also be hard to find. I also use all of the above - when I use a real PDP-11. 99% of the time, I now use an emulator under Windows 98 SE since I require 132 character text lines under KED on RT-11.
