Subject: Help figuring out ICs and ROMs for BBC (B or Master)

Hi,

I got me a couple of BBCs last year, now i have gotten around to
trying them out.

Along with the computers, peripherials and software I got a collection
of ICs which probably are spare parts for the computers.

Now i need help to identify what the ICs are used for and if they are
worth keeping.
I've gathered that the ICs with a "window" are EPROMS (or EEPROMS) and
that the SAA5050 are text graphics chips, but the rest of the ICs are
unknown to me. (I'm not much och a electrical engineer so...)

So I'm asking if anyone here know what they are and what they do.
Images of the ICs can be found here:

Cheers,
