Direct connection to Sony Multi-Interface Shoe?

[mungewell]

I have a couple of Sony cameras without an audio jack, so I was wondering.... and ended up going down a massive rabbit hole.

The Multi-Shoe is described:
https://en.wikipedia.org/wiki/Multi_Interface_Shoe

It seems that (at least for simple devices) that the function is 'encoded' on the first 3 pins, as pull up/downs. It looks like for analogue audio that there are connections on:

• pin 4 - Mic GND
• pin 5 - Mic Right
• pin 6 - Mic Left

also

• pin 7/15/21 - Power GND
• pin 13 - Regulated power (3.1V)
• pin 14 - Mic Center(?)
• pin 17 - Un-reg Power (6.1-8.4V)

There are also some Digital Mic, with a digital connection to the camera(s), I presume that's the GVIF_SDATA_N / GVIF_SDATA_P alternate signals on the same pins.

There is a database of mics, and what they are supported on:

The real question is whether there's a cheap/easy way to get a compatible connector? Can we re-arrange the pins on a
Sony ADPMAA adapter?

There's another description here:

And Sony make an adapter for some wireless kit:

It also appears that the (older) Nex-3/5 also supported a hot shoe mic, but the connection is different (vertical plan, rather than horizontal).

Multi-shoe replacement connectors intended for repairing flash guns are now appearing on eBay for around $15. This might be hackable, to move pins to places we need them...

The XLR-K1M mic adapter has a flying lead connection to the hot-shoe, which is available as a spare part - though kind of expensive....

There's also an extension cable for use with the XLR-K3M:

This is the hot-shoe connector from the FX-3's TopHandle, XLRH1:
