Caveat
In order to install the adaptor you will need to remove the motherboard from the A500 case temporarily, install and put mobo back with the adaptor on. There is not enough room/clearance to install through the sidecar port opening of the A500 case.
86-pin connectors I sourced from here:
https://www.aliexpress.com/item/33029711948.html
While installing you might want to put a solder blob or put a 0 Ohm resistor on JP6 (Rev.6A mobo's) to connect through the 7 MHz clock. On Rev. 8A (A500+) it is already connected with a track on the PCB. I put a 0 Ohm resistor in picture below, and then put back the protective metal plate.
The adapter clears the keyboard nicely, but not if the inserted card is too bulky towards the keyboard underside. The CPU fitted in the OpenAmiga2000CoproAdapter on picture below touches the keyboard underside, but this was only for temporary testing the edge adapter anyway.

Questions
How big is the A500 86pin internal adapter PCB?
It measures 128 × 25.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the A500 86pin internal adapter use?
3 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the A500 86pin internal adapter KiCad files?
From the jbilander/A500_Edge_Expansion_adapter repository on GitHub, at the commit this page was made from: the board is KiCad/A500_86pin_internal_adapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the A500 86pin internal adapter design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
