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).
