Full length Zorro II which allows the addition of up to 8MB of RAM. There are several versions of the MegaMix card, two of which are shown here. The three DIP-switches control the amount of memory. The revolutionary thing at that time was that it could hold LESS than 2MB of memory. The first 2MB were made up from 44256 ram chips, so the smallest configuration was 512K. Next step was 1MB, and 2MB with all 16 chips installed. The SIP modules have to be added two at a time, because they are only 8-bit wide. SIP modules have the same pinout as SIMM modules, but the company wanted to save the money for the expensive sockets. The board can be easily equipped with SIMM sockets.

The two jumpers can swap the 16-chip bank and the last SIP bank. This allows using the board without 44256 chips, because the chip-bank becomes the "last bank".

Please note that the second image shows a Megamix card which is almost identical to the Masoboshi Fast RAM 2000 card. The only difference being that the Masoboshi card shows the manufacturers name in the corner. It is currently unknown whether this card was sold under license by either Masoboshi or 3-State or one company later became the other.
