c46 is 680uF, 35 volt LOW ESR
c59 and 58 is 100 nf
Floppy connector, remove pins like on photo, 1,2,3,7 (on this pins is 5 volt power)

U28 is Attiny 2313A, PS2 keyboard controller ,hex file and topic about it is here http://www.cpcwiki.eu/forum/amstrad-cpc-hardware/is-there-any-recent-project-to-connect-a-pc-%28ps2%29-keyboard-to-the-cpc/new/?topicseen#new
Or contact with me and i post programmed Attiny to You.
Change resistor R64 to 150 R
change resistors R34 and R40 to 20 Kohm Add 10k resistor between U5 pin 9 (or R30 like on photo)and +5volt
