[...] a connector I've never seen before.
It's a D shaped shell
which has 3 holes side by side no more than .25 inch in diameter. In
each hole, there's a small pin. What in the world is this?
This sounds a lot like a 3W3, such as is used by (for example) the DEC
3000/300X Alpha machines.
I have such a machine. I scanned that end of the cable I use with it;
the result, converted to jpeg format, is at
ftp.rodents.montreal.qc.ca:/mouse/misc/3W3-scan.jpg for your perusal.
In passing, does anyone know a source for such cables? While removing
it from the machine, I discovered - the hard way - that the connector
stuck to the machine more strongly than it stuck to the (molded-on!)
shell on the end of the wire. I've pushed it back physically, but I
have little confidence it will actually resume working, so I am
probably going to be searching for a suitable cable.
