this is a Fujitsu 3rd generation leaf spring keyboard project based on xt layout, I just finish it these days,and it's fully tested, now I decide to share this project, I only got a few Fujitsu keyboard sample, so my pcb can only support two types of layout.

the vintage Fujitsu logo

About the layout the layout cames from two keyboard
the fitst one is a fujitsu oem keyboard for the great wall 0520A computer system in early 80s, it's pretty common in china.
and the layout can be found in many different type of fujitsu keyboard.
the length of the main key area is 0.25u shorter than modern standard keyboard.
these two layout have the same 8u space bar and the same cutout on the plate. only one type of stabilizer can be found in this keyboard, the 8u space bar the second one is more like ISO layout.
multiple types of stabilizer can be found in this keyobard, all the cutout can be found in dwg files.
the ISO enter
the 2.75u right shift
the 2.25u left shift, notice the housing on the plate is the same as 2u keys, but they got different length of stabilizer wire
most of the slider and switch modules came from this keyboard, it looks like crap,but the switches are all functional and sliders are as smooth as new. this keyboard is a clicky switch version. here's the testing board that I build earlier about the soldering
need to lift the pcb up with some pillar, and tape the switch module on the pcb the led key caps,uses 3mm leds, need to lift up for 5~6mm with this tiny spacer. and the final work……
hope you guys enjoy this

will post some typing demo later
