Gilsoft

Gilsoft were based in Barry, South Wales and was run by Tim Gilberts.

Most notable for their adventure writing program The Quill, this was the only Sinclair QL program which they released, whilst they went on to develop other programs to allow you to add graphics to adventures created with The Quill for other machines, such as the Sinclair ZX Spectrum, BBC-Micro, Commodore C64, Atari and Amstrad CPC computers.
