47µF 16V.
But they are probably not needed when the SRAM sockets/chips are not present. On one of the pics they are present, although no SRAMs are populated. I guess they were either dropped during the production period or they have been present on your mainboard and were removed later. The latter would be visible when you inspect the soldering spots closer.

BC115 - BC129 are also present but not needed when no SRAMs are there.
TC30 and TC31 are for filtering Vcc and preventing transients. They make perfect sense when SRAMs are active and they won´t hurt otherwise.

They were both present, but were torn off (before i got the board). In my image, the remains of the legs are already soldered off.
The remains of the stripped cases were in the packet with the motherboard. On the remains of the cases I see on one 47µF 16V, and on the second 100µF 16V.
It is impossible to understand which of these places each of them occupied previously.

You can round up capacity to 2 x 100µF without any risk here.

Ok, thank you for information.
