The Imlac uses a Winchester connector (14 position) for the display and
while they're not as common these days the parts can still be found so I
thought I was in the clear, but what I failed to notice is that three of
the "pins" (for the X, Y and Blank signals) are actually tiny coaxial
connectors that fit within the Winchester housing (i.e. they're the same
diameter as a Winchester pin).
What is a "Winchester connector"? Do you
mean a D-sub connector, i.e.,
with a trapezoidal shell such as you find on terminal or VGA connectors?
Those come in a number of widths, with names like DE (for the VGA size), or
DB (the 25 pin classic RS-232), and so forth. Often, incorrectly, all are
called DB.
Those shells have a variety of choices for pins. They may be two rows of
pins (e.g., DB-25), or 3 rows (e.g., DE-15). You may also find ones that
have just miniature coax inserts, or a mix of coax and plain pins. The
coax inserts are generally larger, such that it takes up much of the height
of the connector. I haven't seen coax pins that are the same diameter as
plain signal pins, that's rather hard to imagine especially for something
as old as an Imlac. Examples of mixed pin D-sub connectors are the Sun
video monitor connectors, with RGB on coax.

Sorry for not being more specific. The coax connectors in a 13W3 connector
(for example) are much larger than what I need.
