That reprisents the holes in your surfboard.
It's for a sb5100.
If you had one and opened it,you would realise.
The first thing i ever made was a max233 for cloning the ambits.
It took me a few goes,but got there in the end,it felt good.
I'm getting a jtag i bought off ebay which i think might do the same as the blackcat with a bit of messing,but i'll test it before i go shouting about it.
That diagagarm is a bit like the london underground map.
It has no real relation to where things really are,just where they go.
A bit like a game in a puzzle book.
Pin one goes to pin three, pin 7 goes to pin 4.
Then 4 hours later you made yourself a working blackcat!!!
But in my case it was a week later cos i was missing the 5v!!
If you got a soldering iron have a go!!
