derek ,

please post the details , i am really interested.

Here is a photograph of the underside of a standard QL ROM card, with some wiring mods.

This allows a eprom to be programmed with the QL ROM and other Toolkits that would fil the QL ROM space.

Note that the internal QL Roms must be removed otherwise there will be a clash in Rom chips.
