The Amstrad CPC version was Quilled (according to a later Recreation Re-creation advert). There was also a later version available for disc-based Amstrads that was created using CP/M PAWs.
The Spectrum version was produced by Philip M Reynolds using the PAW. The Spectrum loading screen is credited to ANT, probably Tony Collins who first published that port on his The Guild label.
When the Spectrum version was sold by Adventure Probe Software (c.1994) it was advertised as being available in both 128K single-part and 48K double-part versions.
