Hi folks,
I have a slight problem here.... Several months ago, I disassembled my
Sirius-1 to try to ascertain why the hard-disk was not working. I've not
actually got any further with that yet, so I decided today to re-assemble
the machine, a) because I was fed up of the bits all lying around getting in
the way, and b) because I was worried that I might lose some of the screws,
etc.
Now, the problem... There's a whole stack of connectors which come out of
the FDD drive, and hook into a big long set of pins on the board which sits
over the top of the disk drives. I did make a note of which went where, but
that's on my "normal" computer, which is currently in Spain (unlike me)...
So - does anyone know what order the B: drive connectors should be plugged
into on the drive board?
The connectors are marked thus (switch to a fixed-pitch font for clarity):
MX-9 (2 off - I shall call them MX-9a and MX-9b):
MX-9a has 5 pins & 4 wires coloured Yellow, Green, Red, Blue
MX-9b has 4 pins & 4 wires coloured Black, Green, Brown, Red
MX-3 has 3 pins & 3 white wires
MX-19 has 4 pins & 2 white wires
MX-8 has 4 pins & 2 white wires
MX-11 has 4 pins & 4 white wires
Note: Where a connector is not fully populated, all wires are in LH-most
positions.
On the circuit board, the positions are marked out for the connectors thus:
B21 aka J8 has 5 pins (MX-9a)
B11 aka J9 has 4 pins (MX-9b)
B9 aka J10 has 4 pins
B22 aka J11 has 3 pins (MX-3)
B8 aka J12 has 4 pins
B12 aka J13 has 5 pins
I've guessed at MX-9a & b based on the no. of pins & length of wires (MX-9b
won't stretch much further than position B11/J9); and MX-3 seems obvious
because it's the only 3-pin connector. The others, however, are a mystery
without my original reference...
So, Q is: Does anyone have a Sirius-1 they could pop the top off to have a
look at what order the connectors are in?
Also... And this one I *didn't* make a note of (more fool me); next to the
power brick are 2 MOLEX connectors going to the HDD. Both plugs (HDD side)
have 4 wires coming out - one has 4 black wires, the other 4 white wires. On
the PSU side, one socket has four black wires, the other has 2 black & one
white wire, and a gap. Any idea which goes where? I'm guessing you'd need a
hard-drive equipped Sirius to determine that one...
Many thanks in advance!
Cheers,
Ade.
