Memory expansion for the desktop Amigas (Amiga 2000, Amiga 3000, Amiga 4000) fitting the ZorroII slots.
The card was preinstalled with 2 MB RAM but could be expanded to 4 MB, 6 MB or 8 MB by adding more groups of 16 1Mx1 (511000) DIPs (70-120ns).
A fully loaded board of 8 MB would require a total og 64 DIPs.
Board was fitted with a jumper for enable/disable.
