Some little progress:

On of the 74HCT245T buffers is now fitted.

The other one has to wait, due to 2 or 3 tracks not having continuity.

The RTC is also soldered and has one track fixed (blurry pic):

That's all for today.

Lovely work I have to say, well done.

@rubber_jonnie

Thanks, but it's not over yet.

I keep my fingers crossed and I hope the machine will live again.

And for fun, I powered on the A5000 (without battery, and track repairs still pending) and was greeted by this nice screen, with a cursor only.

At least, there's a sign of life...

Did you try booting with Del held down? Should reset the cmos and boot up to Risc OS from ROM.

[HigashiJun]

Yes, but nothing happened.

The cursor appeared after another key was pressed ('R' or 'T')...

It was just a try and I didn't care too much... Some jumpers may be incorrectly set, and some tracks are still left for repair.

To reset the CMOS it's hold down R and power-on on most Archs.

From what I can see, R or Del should do the reset, and it 'should' work, but I think the next step would be to get the floppy drive connected up to see what, if any, the blink codes are.
