I grabbed the manuals, thanks! The power switch is a bit sticky, so I need
at least to try to fix that, so the service manual may help.

Yes I do have the actual pods. They look like the picture in this listing
(not the item I bought): http://www.ebay.co.uk/itm/152233591570
So, yes I have the pods, but no connectors

I will buy a set and see how it goes. I also believe there are some probes
that are designed to clip over a whole IC, any recommendations for those? I
did try using one once but it was designed to be used in conjunction with
grabber clips and it was so fiddly that I gave up, so I am wondering if
there is something better.
