It is used on the external end of PCMCIA cards

The PCMCIA business is pretty dead now...

I don't mind if it has a cable attached to it. I believe there was an IDC version, intended for some obscure-pitch ribbon cable

Heavy googling finds some products which might be using this connector e.g.

but none seem to exist anymore

and this one is probably the closest since the PCMCIA card is actually an ARINC429 one from MAX Technologies. It is incredibly expensive but I got it on Ebay for about $200 and I am trying to get it working, just enough to be able to monitor ARINC429 packets.

Many thanks for any pointers :)

I've used Hirose connectors in the past, but looking through my notes shows they weren't close to what you want:

I take it you've aleady contacted Hirose?

Hirose cannot be contacted without a lot of hassle.

This is deffo 68-pin; I counted them and you can see them in the screenshot.

looks like a 68 pin external SCSI III connector. check a dumpster, lots of them out there.

Those are indeed very similar but they are wider.

I made a little PCB to fit into it. 0.8mm pitch, 0.8mm thick, gold contacts, and 30 bucks from china for 5 of them.

Interesting, what is the size difference?

The SCSI connectors on PC cards are about 2x bigger.

I just measured about 31.5mm across the shell of the SCSI connector next to me. Maybe 47mm-ish between centers of the screw parts. No way your connector is half that size.

It is wider the other way :)

The width of this connector is about 3.5mm.

About 37mm across the screwlocks.

I typoed 47. it's 37mm, the standard for ultra high density SCSI. Either way, it's a common connector.

I have some SCSI cards with this connector style but not the 3.5mm wide.
