The Twentieth Anniversary Macintosh uses the same logic board and memory as the Power Macintosh 5500 and 6500 series computers. Like those computers, the Twentieth Anniversary Macintosh does not have any DRAM memory soldered on the logic boards. All RAM expansion is provided by DIMMs installed in one of the two 168-pin sockets. It includes 32 MB installed in one of the two DIMM slots.
