Atomwide A5000 4-8MB Upgrade (1993).This upgrade is only suitable for the late model A5000 with serial numbers ALB32, ALB27, ALB28 or ALB35 which have a socketted MEMC1a.The smaller board has a plug on the bottom which plugs into the MEMC1a socket on the A5000 motherboard (once the existing MEMC1a has been removed!). On the top are sockets for 2 MEMC1a's, a master and a slave, each of which can control 4MB memory giving a total of 8 MB.The larger board plugs into the 4 RISC OS ROM sockets (after the ROMs have been removed) and contains 8 x MB81440A-70PSZ (4 x 1Mb DRAM) giving 4MB RAM in addition to the 4MB on the motherboard. The RISC OS ROMs are then installed in the sockets on the board.
