The 1403 attached to S/360/370 via a byte multiplexer
channel ...
The question is, did they have a way to attach the 1403 to any of their
computer systems?
There's a thing called a DX11:
https://gunkies.org/wiki/DX11-B_System_360/370_Channel_to_PDP-11_Unibus_Int…
which attaches a "selector, multiplexer or block multiplexer channel" to a
UNIBUS machine, which sounds like it could support the "byte multiplexer
channel"?
The DX11 brochure only mentions that it can be "programmed to emulate a 2848,
2703 or 3705 control unit" - i.e. look like a peripheral to a IBM CPU;
whether it could look like an INM CPU to an IBM peripheral, I don't know.
(I'm too lazy to look at the documentation; it seems to be all there, though.)
Getting from the UNIBUS to the -10, there were off-the-shelf boxes for; the DL10 for
the KA10 and KI10 CPUs, and a DTE20 on a KL10.
It all probably needed some coding, though.
