Short clip showing SPARCstation 2 with working stacked memory expansion boards in SBus slot 1. Each board with additional 32 MiB of RAM, so 64 MiB if stacked. If all memory SIMM slots (banks 0..3) will be populated on mainboard and the primary (SBus 501-1823) with secondary (stacked 501-1824) memory expansion boatds are installed, youre able to max out the RAM capacity to 128 MiB. The memory expansion boards is connected by a flex cable from primary expansion PCB directly to a dedicated connector on the mainboard of the SPARCstation 2. In comparison the dedicated connector isnt available on mainboards of SS1/1+ models
