I ordered a MiniTools test clip to start experimenting with flashing EEPROMs. There was no information on the retailer's website regarding the width of the pins. This is what I got:

I asked MiniTools if they have any solution to this. They said "no". I then realized that this clip was probably meant for soldering. Which I haven't had the energy to learn yet.

I ended up buying the expensive Pomodo one.

The flashing went well.
