This time for flash: specifically, the S29AL008J and any equivalents.
It uses a Nucleo-64 as the controller, because (a) I had some and (b) and it has enough legs, and needs two bits of software still to be written: one for the Nucleo and one Linux terminal program.

The part uses those TSOP-48 ZIF sockets that are all over the bay for a couple of bucks each. For reasons known only to the circuit board demons, I managed to put the alignment holes in the wrong place but it's just a plastic pin that easily cuts away. It needs to be removed from the converters anyway; there isn't room for the hole. Oh the embarrassment

I also made a pile of converters that will allow the bottom 32k of the flash as a 2x256 equivalent in 600 DIP/28 (as an aside, does anyone know where I can get 'chip' sized flat pins to use instead of a pin header on such parts? I've seen them somewhere, but I'm blowed if I can find them again).

DIP adapter, with DIP28 for comparison.

Are you thinking of FlipPins?
http://oshchip.org/products/Flip-Pins_Product.html
They seem pricey, but they look cool. It also looks like they are discontinuing them, as they only show availability on the OSHChip Tindie page.

Thanks Sam, the page you linked doesn't load for me, but using the name I found https://hackaday.com/tag/flip-pins/ which is pretty much what I had in mind.

Ah, looks like a problem at searchivity, wherever that is. But in concept, yes.
