HSP/Serial Port Question

Hello, I was wondering if anyone knew what kind of sockets these are. Mainly
because I'm interested in making some hardware for them, or to use them for
I/O etc. However you can't really do anything unless you can interface with
the connectors.

I'm thinking these aren't standard sockets, but I was wondering if that was
true. I could fudge the 2 serial connections using a hobby pcb kit, but the
HSP would be another matter. Anyone have any suggestions on what plug to use
in any of these sockets?

Oh, btw I'm new, and interested in practicing what I've learnt at uni =)
Nice to meet you all.
