Status

This is tested and working

Features

• 8MB of Fast RAM
• Auto-sizing - The RAM board will coexist with other devices by autosizing to fit the remaining free Zorro II memory space

PCB Ordering

For best results the boards should be manufactured with the "Gold Fingers" option so that the edge connector will survive many insertion/removal cycles

Jumpers

4MB: Forces the board to appear as a 4MB board rather than 8MB
