Worth pointing out is that RDxx device sizes on RQDX3 and on the Pro are not the same, because the Pro always uses 16 sectors per track even if the device has longer tracks. Also: the device needs to be formatted. paul

I'm using several of these, on PRO380s, and on RQDX3s on MicroVAXes and a BA23 11/73. Lessee, did you create the container file for the disk? And make sure it's the same file name used in the command line that starts up the service? Did you do the command that tells the service to start at system boot time? And, my favorite problem in setting these up - are the cables plugged in right on both ends of both cables? I had to span the vector space of linear combinations of plug orientations to get it to work, since my cables didn't have keyways, and how to plug 'em in was not obvious. When it works, it works great. Only problem is that I have to pause a bit after powering on the system, to let the automatic file backup finish before the 11/73 tries to access it. If you don't get anywhere, David Gesswein is very helpful sorting out problems. -- Lee K. Gleason N5ZMR Control-G Consultants lee.glea...@comcast.net

I figure there must be a configuration that needs to be done, but found nothing in the documentation to do it. Have you tried contacting Dave Gesswein directly? He's usually very responsive to questions, and is a DEC guru. https://www.pdp8online.com/ Mike Loewen mloe...@cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/
