Atomwide 8Mb RAM Upgrade (1991)

The Atomwide A5000 8Mb Ram upgrade can upgrade an A5000 from 2MB to 8MB. This card only has 2MB in 16 x GM71C4256AZ-70 RAM (= 16 x 256k x 4 = 2MB) and is also missing components on the right. The card fits on the A5000 memory expansion.

To address a further 4 MB a second MEMC1a is required. On this card the MEMC1a on the motherboard is removed and a plug on the bottom of the card would fit its socket, the MEMC1a is then added to a socket on the top of this card. An second, slave, MEMC1a is installed on the card with the additional 4 MB RAM.
