So I know for certain that this topic has come up before, but I cannot
for the life of me find the thread(s) it appeared in, so I'm asking
again (apologies in advance).
What is the name of the rounded, 3-pin power connector often seen on
early test equipment (I've seen it on older HP and Fluke stuff)? I have
an S-100 chassis that inexplicably uses one, despite dating from 1982 or
so. I need to track one of these cables down but I have no idea what it
is exactly I'm looking for...
Thanks as always,
Josh

The trade name is 163.

consistent but the hot/neutral were wired two different ways. Did I make this all up?

IIRC the ground lead may not be consistent. I have the non-HP-pinout 163 cords set aside,
but I don't know how soon I will have a chance to check them as medical problems are
slowing me down.

There's a discussion of the '163'-type power cords here,
http://www.cs.ubc.ca/~hilpert/e/powerConn/index.html
hot and neutral were swapped depending on which "standard" was followed but
ground remained the same.

Yes, there where two different type each with
different hot and neutral. Luckily, most equipment
with these have transformers. With a GFI socket there
should be no issue.
From some recent reports, no major wire maker is still
making these.
It seems there may be a small market for an adapter.

Is it a Cromemco? Inexplicable is right. The Cromemco Z2 S100 chassis from 1978 used them,
I don't know what they were thinking using it that late, unless they got a deal on a

Yep, that's exactly what I have -- it's a CCS 2200A. It's a nicely

I've purchased a suitable power cable, thanks to all for pointing me in

============
Are you sure it was a Cromemco Z2? If so, it must have been a really old one; I've
seen quite a few Z2s in my time and they all had/have modern IEC type line cord
connectors.

Yup, this:
http://www.cs.ubc.ca/~hilpert/tmp/CromemcoZ2A.jpg
IC date codes on boards were 77 to 78.
Presumably bought as a package as it had Cromemco ZPU, TUART, 4FDC & 16KZ boards.
I replaced the 163 connector with an IEC.
As a matter of fact here's an example with the 163 connector:

Yup, indeed definitely a 163 in Marcus' picture; my time selling and supporting
Cromemcos starts in 1980 and by then all models including the Z2 had IEC connectors.
As a matter of fact, from the copyright notice it looks like the Z2 rear panel and P/S
were changed in 1979:

Are the inlet connectors in question simple connectors, or are they part
of an RFI filter assembly? Pretty sure we had to have RFI filters on
Century disk drives field replaced in the mid 80s that still had the 163

FWIW the IEC versions were slightly oversized integrated filters.
