This is a card for Fujitsu FM Towns Marty console (both 1 and 2 models) that will add to the system further 2MB (4MB in total) allowing you to play some games that do require 3MB or 4MB of RAM (like Super Street Fighter II and others)

The card plugs into the rear expansion port of the Marty console (you need to break the plastic tabs of the cover in order to access the port), see picture above.

BE CAREFUL TO NOT BEND THE CARD WHEN PLUGGED INTO THE PORT OTHERWISE YOU MAY END UP TO DAMAGE THE CARD ITSELF AND THE PORT!

For v2 revision (smaller board with ON/OFF switch) users :

PLEASE, TURN OFF THE CONSOLE BEFORE USE THE ON/OFF SWITCH!
DO NOT USE THE ON/OFF SWITCH WITH POWERED CONSOLE!
