Hello, Tony,
Thanks for the reply.

Of course it requires a different device driver. ?
I know them as Terminal Blocks.? The intention here is to connect
Teletype Model 33s as well.
I'm trying
to free up slots in my PDP-11, so I'm looking to remove the DL11's I'm using
and want to replace them with a single 20ma DZ11. Does anyone have a DZ1
Firstly, I am probably telling you what you already know, but the DZ11
and DL11 are totally different in software. If you are doing anything out
of the ordinary and have sustom drivers you ahve a lot of work ahead. 1 20ma
dist panel they'd part with?
Soecondly, IIRC the disptribution panel is essentially just connectors. I
have a few of the even older DJ11 muxes and a couple of the distirbution
panels were home-made. Berg conenctors on a bit of square pad board with
wire-swap wire goign off to what we call 'chocolate blocks' [1]. Looks a
right msess, but apprently it was used at a university to conenct up
ASR33s for many years with no problems.
[1] Does that term mean anything to you? It's a common term over here for
thos plastich screw terminal blocks Modern ones are norally white,
flexible plastic (nylon?) the very old ones were a brown brittle themoset
plastic, hence the name. Given that the current loop signals are pretty low
speed, you would
almost certainly get away with taking a length of ribbon cable, putting a
BERG socket on one end, splitting the other end into individual wires and
puttign them on screw terminals.

I'm specifically looking for the DEC distribution panel at this time, but
thanks for the suggestion though.
