Well, I've resolved the situation partially.
It was time for me to upgrade my MacBook Pro to a newer model anyway
(and pass on my 2006 MBP to Alma) so I've managed to get a 2010 MBP 2.53
(8GB RAM) with the hi-res anti-glare screen in mint condition boxed for
785 GBP. I've ordered a 250GB SSD for i

Yup. Screen brightness increases, except the screen is dark. It just

First thing I tried!
Also reset the PMU - all to no avail.

for the sake of argument and just to see if it is doable, while her sick

no; but there may be enough info in the model # etc. to look it up and get the
part info;
Bruce has it right. In target disk mode, there is only the base chipset to
make the drive available running. Everything else has been bypassed.

Steve, as I understand it, when a Mac is in Target Disk mode it's
running off code in the boot ROM and isn't running an OS at all. So
it's single-tasking and there's no way to get it to do anything else;
probably just as well.
