Hi all --
I'm in need of an RL02 cable (drive to drive). I picked up a second drive
for my PDP-11/40 and I'd like to get it hooked up.
Thanks as always,
Josh
I don't have a spare, but just to follow up on our earlier conversation I
was able to remedy the DC LO issue on my 11/40 so I could work on 15V going
to the RL11 controller as you suggested. One issue remains however.
When I power on I get the correct quiescent lights, but address line 16
comes on when one pressed the LOAD ADDR switch for any address, (and paddle
16 was not up)? Same effect if I switch out RAM, it's not caused by the
RAM nor the M9312. I still get this effect even if I have no RAM in the
system. I thought for sure this was a specific error, but I can't seem to
find it in my notes or docs. I have seen this before. M7231? If you know
great if not I will keep looking and testing. I am very encouraged as to
your progress with the 11/34 and I hope soon to finally get my 11/40
booting with an RL02.
