Futaba switches
Underside of space bar, and stabiliser assembly
The space bar stabiliser wire clips into something that sits around the base of two of the switches; there are plate and PCB holes for dedicated stabilisers as found on the Memotech MTX 512 but for whatever reason, a different approach was substituted after the keyboard was designed.
Yellow braided LED legs; in my loose keyboard the braided sheath is green
