That is pretty much as I expected, as in similar to MMU adapters. Not dissimilar to the way Alan H's IDE board plugs into the PLCC socket, albeit with a CPU in place.

I guess the question I have, is when plugged in like this, does the plastic square support the PLCC socket spring connectors enough, since it doesn't have contacts that extend outside of the dimensions of the square, like the CPU does, which would normally put pressure on the PLCC socket contacts when the CPU is installed.

I hope the way I explained that made sense, otherwise I'll have to draw you a photograph :o

Don't know yet :)

I guess if Troed is printing them, he can add the "dummy pins" to the CPU as well if needs be.

Fair enough, would be good to see the results from both options. Shame I don't have a 3d printer myself, or I'd give it a go. Maybe later in the year....

If anything, the squares might have to be fraction smaller than the CPU. Square is actually quite hard to fit in even with just one row of pins inserted.

Are the pins hard to fit if the square goes in first?

I tried one row, needs a bit more of a push as expected. Still pretty easy.. just aligning all 4 to the socket when inserting the booster is the hardest part.

What type of pins should I test with?

Basically I made one with the exact measurements you gave and printed on "high quality" and it fits really well ... but if I can test myself before sending to you I might be able to iterate the design somewhat :)

Looking nice! I am not sure what the pins are, I think they are 1mm pitch.. Maybe Best if I post you a few strips ?

I'll try to source some locally :) The pitch is 1.27mm?

If so I can get headers from here when driving home from work: https://www.electrokit.com/stiftlist-1-27mm-1x40p.51493

Bought a good caliper today to check what accuracy I got from the printer. 24.35x24.40 (from 24.40 in the CAD model). I'm happy with that ...
