512K Expanderam
The 512K Expanderam was produced in large quantities by Miracle Systems.
It consisted of a short card carrying 512KB of dynamic RAM and was a version of the Miracle Expanderam.
The Expanderam plugs into the QL's expansion port and has a through connector to allow you to plug another interface (for example a disk interface or an EPROM programmer into the end of the expanderam). Included in the box was a metal (or black plastic?) sliding cover.
A 256K version was also sold by Miracle Systems for £95
