Inicron's ROM-RAM-Box is a external device connected to the expansion port(with pass-trough), that provides 512 KB Pseudo-ROM.

Technical specs.

Inicron produced 128 KB and 512 KB ROM-RAM-Boxes. Both used S-RAM to simulate ROMs. The S-RAM is buffered by an accumulator, that is charged by the CPC. The contents of the Pseudo-ROMs remains stable for about one year.
