I had one of the ends of the 50-wire flat cable get damaged and replaced it. But it is possible either I did something wrong, or the cable itself also got damaged. I don't have anymore of those but I have a new one on the way. So I'll see when I get it.
Yeah, the CSR is the factory 172150, and both XXDP and RT-11 see a controller on that address. It gets a vector of 154 which also seems reasonable compared to my 11/23+. - Peter On Fri, May 23, 2025 at 10:03 PM Wayne S via cctalk <[email protected]> wrote: > Csr correct? > > Sent from my iPhone > > > On May 23, 2025, at 16:58, Bill Degnan via cctalk <[email protected]> > wrote: > > > > Cable and termination? > > > >> On Fri, May 23, 2025 at 6:48 PM Peter Ekstrom via cctalk < > >> [email protected]> wrote: > >> > >> Hello to the group, > >> > >> I have been banging my head against a PDP-11/23 where I have an RQDX3 > I'm > >> trying to get to work.
