This type of expansion installs under the TED and is extremely compact. It uses modern static RAM which uses a trickle amount of power. It uses special thin pins adapted to the peculiar (as in dirt cheap...) 48 pins socket installed by Commodore in the C16 and C116.
NO MODIFICATIONS REQUIRED!, no bending of pins and very small size. Comes with a switch to toggle between 16k/64k - a reset is required when switching between these modes.
Abilities in electronics, and soldering skills may be required if you have no socket or its damaged before installingthis item.
