Currently, the above repository is only available securely via the following 
address:

https://git.hands.com/?p=eoma.git;a=summary

Meanwhile, I updated the wiki page describing PCMCIA/CardBus component 
details:

https://rhombus-tech.net/pcmcia_sources/

(Thanks for Phil for fixing the wiki!)

One interesting thing that came up, given the conversation that was had over 
two years ago, was this product and corresponding brochure about PC Card 
casings and tooling:

https://www.ittcannon.com/products/starcard-snappy/

https://www.ittcannon.com/Core/medialibrary/ITTCannon/website/Literature/
Catalogs-Brochures/PC_Card_Final.pdf?ext=.pdf

On page 37 of the brochure, there are some pictures of the tools that would be 
used to facilitate assembly and disassembly. I seem to remember complaints 
about assembly, and I found some remarks on this list from back in 2017...

"the litkconn P/N 68F casework basically is a "total disassmbly" job.
it's a pain in the ass and takes several minutes."

In the crowdfunding updates, the awkwardness of assembly is also mentioned 
here:

"Additionally, I am considering sending out the PCB and casework unassembled, 
with full and precise assembly instructions for backers to follow. It’s not 
hard: it just needs to be done very carefully. This will save a considerable 
amount of time and money, as the cards casework will need hand-assembly 
(quantity 1,000)."

So, I guess that with the above product family, one would want to invest in 
that tooling as well as the actual products, just to do things as the 
manufacturer intended. It is an interesting insight into part of the process 
that goes into making the product.

I also had a bit more luck searching for product documentation today and also 
found this:

https://media.digikey.com/pdf/Data%20Sheets/Hirose%20PDFs/NX1.pdf

The product itself is about to be discontinued, but there's an interesting 
pictorial assembly guide including a picture of an assembly jig.
