[BBC-Micro] Disk fault 0C at 00/00

[Anders Carlsson]

Hello again,

as an update to my own post, I opened up the computer and it
looks like this: (big, blurry image)

That is, some kind of expansion card in one of the ROM slots, and
a total of 11 wires: 2 to the CPU, 3 to a 6522, another two each
to S20 and S21, and the last two to IC76. The board is an Issue 7.

I know as much this computer came with a Music 500 expansion that
I didn't buy because the seller wanted a lot of $$$ for it and I
can't see myself use it. Would all these wires inside relate to
the Music 500, and should it in any way interfere with floppy drives?

I suppose it is the unlabeled 2762 in IC52 that contains the DFS,
in case I should replace it.

Best regards
