I see the ones you're looking at.
They're capacitor networks, I.E. 8 capacitors in 1 package. They're a
bit specialised and sometimes hard to find though.
The writing says 101kx8 which means there are 8 100pF capacitors.
Looking at the circuit, each capacitor simply sits accross each floppy
signal pin and ground, so they're used for RF decoupling.
That means the board should still work fine without them, but I
suggest keeping ribbon cables as short as possible to minimise
noise/RF pickup.
If you wanted to fix it properly, and can't find a capacitor network,
then here's what I'd do:
Find someone who sells chip components and buy some 0805 sized 100p
caps. On the solder side (bottom) of the board on the actual header
pins, solder each cap vertically between the signal pins (top
row) and the grouns pins (bottom row). One cap per pair of pins.
On the floppy connector every even numbered pin is ground.
Hope that helps,
Anthony.
