To give you an idea of the speed, to program a 2732 on the EMP10 it takes a whole 20 seconds or so depending on the dump size.

You will need at least one module (RAM looking cards in pouch). For the most part you will only need the M1A/M1B module.

It will work with the older EEPROMs like 2532, 2716, 2732, 2764, 27128, 27512 and so on.

Once you start the menu and click on "Select Device" it will tell you what module you need to install into the EMP10.
