IF you own a ZIPSTER Mega Mini MPI, you know that when you plug in a program pack into your MPI they are not very secure. This extension when printed can be screwed into the MMMPI, you will need to also get 2 small screws or M4 bolts. Test the print first by putting in the packs and then mark where two holes need to be made. Take apart the case of the MMMPI and drill out the holes. Then attach the extension onto the top of the case, reattach and your now secure in loading in any larger Packs (like a disk controller etc). Hope this works for you, been working well for us.

NOTE: Need to double check which way you place the extender on top, the sizing is not exact both directions (IE one way is the correct way). This was done on purpose to match the original MMMPI sizing.
