Apologies in advance for what is probably a stupid question. I'm new to the world of electronics and I haven't yet seen it covered in any other posts or Youtube videos.
I'm thinking about how useful an oscilloscope would be, to play with (and maybe create) simple peripheral devices for old computers.
So I can see how a 4-channel oscilloscope would be great to see what's happening, using one channel on the Write line, one channel on the IOREQ line, perhaps a channel on one of the address lines, and who knows, maybe a channel on a Read or Chip Enable line.
On an old 80s era Z80 board, I think I could use crocodile clips to attach the oscilloscope channels to the legs of the big components.
But I wonder, how is this done with newer equipment? Equivalent devices created after the 80s (e.g. tablets, laptops etc) tend to be more cramped, and use a lot of small surface-mount elements. I can imagine carefully(!) holding a probe to a point on a board, maybe two probes at a push. But I have a limited number of hands. How do people manage this in real life?
Thanks.
