The QL ROM Switching Board is a small circuit board, produced by members of the QLEA Quanta sub-group in England. This board allows you to install both a Minerva EPROM plus an original Sinclair ROM into the QL. Either of the two ROMS can be selected by means of a switch and a reset of the QL. The selected ROM is indicated by a two colour LED on the top of the QL case, green for a Sinclair ROM, red for a Minerva.
