SaRuMan 64 is a DRAM replacement board for the two DRAM chips on C64 and C64c boards 250466 and 250469. This little board replaces the two 64k x 4 bits DRAM ICs with a single static RAM IC. Accordingly it consumes only a trickle amount of power, about 5mA. It also acts as a VSP bug fixer. (Illustration similar)
